A few words
The measure is welfare, the sun is the exercise, and now is not afraid to write daily newspapers every day. Compared with the 500-odd public applica- tions, the daily report is simply too small. Aunt Zhang is a good helper on the road to your work. You can see a thing in your customer's room. You can share it with your customers by sharing it with others. So you must always pay attention to Zhang Aunt, of course, Zhang Da Ma. It's not all good. You must pay attention to Zhang Da Ma and you must benefit from it. It's not wrong, it's a benefit!
About papa
The brand papa belongs to the elephant race (it is said that the company name has a plant or animal that doubles the probability of getting an angel). At present, it has been A round, so from the perspective of product purchase, getting the A round will not happen for a short time. There are major changes, then the after-sales problem of the product can be expected, at least when I pay attention to new products, if the angel round of crowdfunding products basically do not consider, because the risk is too high. With regard to the current Jingdong sales, it feels like the work is still not done well, and the pre-promotion is relatively slag. This product is still praiseworthy in the actual test, but the actual sales of Jingdong after opening the purchase is not high (and the strange thing is Jingdong's open purchase price is the same as the official website's F code purchase price, and the official website still isolates the price of 1499. This kind of behavior to JD's price-defense is not just.)

Undressed solution
Now basically abandon the previous drying single mode, because a photo is over a hundred, it is easy to see fatigue when reading, and the text part is not prominent, so now use the same type of photo merger, hope to give you a look at this article Good user experience.
Aunt Zhang did not forget to publicize her products from the early public testing products. Each time the front desk saw a yellow bomb package, that was full of quarterly eyes. Now every time the parcel is delivered to the company, it has become the envy of the gods. The only attack target. It seems that for a long time there has been no measurement of such large-scale products (referring to the amount) that did not seem to have a label that was careful before.
This parcel was delivered at the most intense time in the motherland. You can see the red label. Before the wind did not have this label (maybe I usually compare the express documents). In a special period, you know, especially our office address is Yuquan Mountain nearby.
In fact, the special curiosity, this package is provided by the manufacturer, or Aunt Zhang special custom, the basic fit with the size of the product packaging, Zhang Aunt carefully. 
Papa's product packaging design is very beautiful, all tested products also sent a small stent, but I really feel that some gifts are too cheap, and the firmness is not enough, and the lack of a projector tripod is the most important thing is a small spirit level, with a small The portable tripod for spirit level is not expensive.
Wrinkled, what is worth buying paper or Zhang Ama's thank-you letter last year, this year because of frequent business trips really not to force, long time no drying single, really could not live Zhang Aunt.

Sensual cross-flow
The large collection of products in the package, the main machine is not listed for the time being.
Remote control: similar to the millet box, but the texture is not good for the millet box, some light, and the feedback of the button is good. In practical use, the remote control angle and distance are quite satisfactory, and the range is very big.
Charger and charging line: work can also be, especially the charger is very high quality, very heavy weight. But the line needs to say, some short, I think there is an attitude product, this machine must be equipped with two lines, a 2M, a short line of this kind of 50CM, because in the application scenario this device though Built-in battery, but it always has a long line, it will be more handy to use, and can deal with a lot of complications, at least need to use this long line as an optional accessory.
The manual is now looking more and more not, and it is better to integrate the functions of the manual directly into WeChat. This will be very convenient to use. In rare circumstances, people who do not use WeChat will buy the device.
The product's impression is still pretty, but I think the biggest problem lies in the perspective of the projection box, the feeling of toys, at least give people the feeling is not exquisite, unlike the high-end things, the prominent black part feels the use of plastic It is cheap, and it gives the entire machine a direct low rating.
The surface treatment of the product is very smooth, because it is white, although there is a fingerprint collection function but it is not obvious, giving the first impression is like the back of the previous 4S, touch switch is also very upscale.
The feeling of remote control sensing that if it is round, it will be more upscale than the current big box.
Led projection mouth feels very cheap, directly reduced this machine grade three.
The left focal length adjustment does not feel the scale, and it does not feel. It is easy to use in actual use.
The back slot is very open in Shenzhen, feeling somewhat rough.
Baseboard, I think if this machine can be made into a sandwich-type mechanism, it will surely be high-grade. Of course, at the announcement of the hammer, it has been stressed that the sandwich structure is very difficult to do.
The bottom of the screw hole is not deep enough, there is a gap with the camera, the actual use of camera tripod with this how much trouble.
You can see that the size of the comparison, there is no one 5s wide, portable is very satisfied with this point, of course, I still have some doubts, in the later review will elaborate.

Product parameters
Need special instructions, the reason is to list the parameters of the machine configuration, is for the final product review is based on one by one evaluation of product parameters, so if you are interested in this product, I hope you can see this product parameters, after all, a Projector product parameters are still very important, as important as a camera product, at least I think now to buy digital products, as long as there is a lens product, then the parameters must be able to read out some of the taste.

Application Scenario----Biggest bedroom screen
Based on my understanding of this kind of portable products, since it is a portable product, then it must not be designed for long-term fixed installation. Most of the applications are based on mobile applications. Then the bedroom is definitely the first place where it can play its own specialty, bedroom. Usually not designed as a movie studio, but you know how comfortable it is to stay in bed and watch movies. Especially when families look at the kids' favorite cartoons, at least when I get this product, I will be the first time. Purchased a scaffolding screen and watched cartoons in the bedroom with the children on the weekend.
Based on the home test, the light is controllable, because the bedroom is not the living room, there is no blinds so you need to wait until the night to enjoy the best viewing effect, this product's lumen is limited, in order to obtain good viewing results still need to darken down (if There is a blackout curtain in the bedroom.
In order to evaluate this device, purchased a 100-inch bracket screen (more than 100 yuan Beijing Epson bracket screen)
Because the main reason is to make children have a better audio-visual experience, so pick up the bedside jbl audio (usually charge the apple, can charge two at a time) The speaker of this machine is only sound, but there is no sound effect, can understand because After all, where is the volume?
The first picture was taken during the day when curtains were pulled. It was probably shot when the sun was shining directly on the windows. The curtains in my bedroom were not thin enough, so it was better to understand the projector concept of 100 lumens.
How big is 100 inches? In fact, you think about putting your sleeping mattress (2 meters and 1.8 meters) in front of your feet.
The actual test projection distance is about the length of a mattress, about 2.2 meters or so can normally project 100 inches.
The second piece is a screenshot of the time it was played. You can see that the edge is still a bit imaginary. The projector does not know whether it is a problem or something of my machine. The edges are blurred. At least one side is blurred, and the bracket may be uneven. s reason.
The last one is the contrast between the child sitting on the bedside and the big white, the viewing area is still considerable. The brain complements the concept of a 100-inch screen that is equivalent to four 50-inch screens, that is, 100 inches is equivalent to four. The 50-inch TV is placed in the area of ​​the field.
Based on this application if you don't have a TV in your bedroom (then save the money on the screen, my bedroom is facing the TV), then you can definitely consider the goods, the young couple look at the depth of the film, a family of three Look at the Xiao Huangren is still very good, basically three or four times to go to the cinema money (see the movie oil money parking fee plus meals) can be saved to save the goods, and one or two months to open less The cinema earns money for the camera.
In the end, we added that although the decorative paper affixed to the wall is somewhat LOW, this is a night out. It is very convenient to find a jbl plug at night, etc. It is very recommended, although it is low but it works well. It will not let you think of something after turning off the lights and turn on the lights. Although the light is weak, it can basically solve many things.

Application scenario evaluation----Chen Zhen invited
Since this product is portable, since it is a built-in battery, then it can not help but think of this feature, car shock invitation (car cinema). Of course, I may use words too wicked, but you can imagine the girlfriend with a girlfriend or someone else's girlfriend up to the top of the hill, or to find a secluded place, two people talking together, may have been playing music in the CD, but you Now with new options, portable projectors. This may not be romantic, but it is definitely not a waste, and it should feel good. Maybe it may be too old to understand the young girl's mind, but I really feel that it is necessary to flick these young people Young female literary artists still have some gimmicks.
Because I have a widow of my wife and I have no time to find a little girl who can watch movies in the wild, so I tested it under the garage.
Noise: Based on the noise of the test machine in an acceptable range, if the volume can be (can be connected to the car audio through an audio cable), the noise of the fan can hardly be heard.
Heat: Many people who have used a projector know that the projector is a heating product. This device is not uncomfortable to see a film in the car in the natural ventilation of the car in the spring and summer. Even if it feels like summer in the summer, the summer car must Air conditioning is not good for people. Even though winter is romantic, it does not have the effect of heat sources.
Brightness: I think it's possible to use anyway. Of course, this thing definitely feels more important. For instance, if you drive up to the mountains in Beijing, you can easily project against a smooth wall. It is certainly not a problem to watch movies under the stars under the full moon. That's it (because even if the projector's lumen is high, it's far away and the screen is too big)
Standby: Since this device is used externally, the battery of this machine can watch a movie (no problem in actual test several times). The on-board charging head can basically solve the problem of long time viewing.
Size: Generally, the front is less than one meter. Suppose that the wall you are projecting is a small gap from the front of the wall. It can basically project about 60 inches of square meters. If it can be one meter away from the wall, then you can project a vehicle. The wide screen (the car is generally around 1.8) is enough for you to hi.
Refraction: Attentive friends must see this device in the front windshield refraction, because there is a film on the front file so refraction is inevitable, but there are solutions, that is, the machine is connected to a Bluetooth speaker, the machine is put out to film , This operation can solve many and many problems.
With this basically everything is Maple Garden, haha, you know Maple Garden you will understand.

Application scenario evaluation - office tool
This product is mainly from the introduction of a selling point as a function of the same screen, which is the application of PPT and other functions in the actual office, but I personally have been engaged in very reeling work, although it will also sing or PPT presentations, etc. I think that if this product is used as a selling point, it is far-fetched, or it can only be an emergency, but who will carry it?
Brightness: I think that the only standard for educational projectors is the lumens. Others are all white. Nobody will be in a dark situation. No one will speak in a dark environment. So look at the back of a few photos to understand, are not in the boot state, pull the blinds. The third one is the conference room that we often meet. This is usually the light. If you use this cargo, you have to wait for the light to turn off at night.
Application: Say here it can be said that the goods are not for office use, because the product's built-in battery and portability, can be used as outdoor extensions and many other commercial applications, this is something traditional projectors do not have.
Based on the logic of the office, the general conference room is a projector, and basically at least 2,000 lumens or more, so if this product as a point of view of office applications I think practical value is not.
You can imagine a scene where you go to the customer and tell the customer that you always look at the curtains, and then turn off the lights. I'll show you something dark and if there is always this Okay, haha, you pay too much for this list.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Application scenario evaluation - outdoor viewing
This application is the place that this product attracts me the most, also is the value that I think this product is the greatest and greatest, outdoor view movie.
Entertaining: Look at the first photo. The three children are gazing at the black cat. The sergeant knows it. If you bring your child out for camping, the goods are almost violent. Next to the yellow chair is the other one who came out to camp and saw us put the black cat. The sheriff took a small chair and stopped eating. If parents often bring their baby out to camp, they will know that at the age of three or four, the child is in fact nothing dark to play with. There must be danger in the dark running around. The child is so calm and quiet in the tent. It is even more improbable. Children are generally more excited about camping than adults. Like my buddy's niece likes to read books, get a camp lantern in the tent to read books, talk about the story is very good, my child basically did not play (the time with children with children basically go out to play, so I have never grown up It's a habit of playing with a cell phone or pad) But the child may like us to watch movies. In short, no children don't like to watch cartoons, and it's absolutely wonderful to bring out a camping belt for children (because we are a corrupt camp this time, if we can use a portable screen in the mountains)
The camping places are all lightless (our camp has solar camp lights). Although the equipment is only 100 lumens to use, there is absolutely no problem. Our camp is quite awe-inspiring in the absence of sheltered camp lights.
However, this device is not the only place for the sound effect, so we come out to watch with a Bluetooth speaker, the device then the Bluetooth speaker so sound with a sense of the screen have, and the actual test of external Bluetooth speakers, a black cat Sergeant normally see (No problem for 1.5 hours in 2012 version).
Similarly, if you plan to confess to a girl and you have a video to propose, you can imagine such a scene. In the saddle night of the Tutu, everyone plans to see if you are the one who is the one who has released the video of your proposal. The guest's feeling must be very liked and praised. Similarly, this can be applied to many scenes. For example, she walks in her home area (most of the neighborhoods are dark between two street lights, and of course there are many dark walls). Because my children are not small, I think there may be little ideas. The application of a specific proposal can be played as much as possible.
There was no test in the tent because the five-rod tent I had with my family was strenuous. The inside view of the tent was based on the color of the account and the color of the account. This method must be feasible, but I think the outdoors was with everyone. Share, if you bring a portable curtain (60-inch 39 yuan) with trekking poles and wind rope with everyone watching comedy or worth the wait.
With a few words, who knows the red line in the second picture of the next picture? Is it satellite? (15 seconds exposure)

Product summary
One sentence evaluation: portable and effect reached a balance, if you like to change places to watch movies, then based on this price is definitely worth buying, of course, if the product is priced at 999, then this product can be considered value.
1. Product size and size
It fully meets everyday carrying needs, and it's really like the size of the palm. It's really portable. There are no problems with daily packages. However, I do not agree that this machine is over-designed to consider factors such as portability, which will lead to compromises in performance. There is no problem with the product itself, but whether it is really necessary to be so small leads to lumens and There is a compromise on standby and I have reservations.
2. The size of the projection
This product parameter is only 15-120 inches, this is more than x now measured in another product to be kind, say relatively conservative. The 120-inch spoken here is an effective viewing size. If the depth is large enough, the environment is good enough, and the projected area is large enough, then how many inches is said.
3. Contrast
Due to the influence of ambient light and the limit of brightness, this product feels contrasting.
4. Operating system
The evaluation did not waste a separate effort to comment on this Android system, because I did not use the player's own playback software (post-installed magic video) at home or on the outside, as well as those provided by the online program for viewing. Very simple because the portable device must be running, then I default to it in a lot of non-network non-fixed environment (if there is a fixed network, why buy portable) the entire software interface is no different from most of the video box.
5. Fluency
Caton situation is still there, no problem in the actual test 720P, 1080P original code of more than 20G more difficult to play a single file, based on the resolution of this device itself out with 720P video enough, because the advantages of this device itself is portable, Therefore, resolution and other aspects must not be strong, as long as it is enough for us.
6. Play time
In practical tests, there is no problem at all between about 1.5-2 hours in a non-cryogenic outdoor environment (not in winter). Meets a viewing time in the device description.
insufficient
1. No lens cap is designed
The portable product is not designed to cover the lens cover. It is not understandable because it is portable so it should be brought out. The device that is brought out does not involve lens protection. This is hoped that the second generation product can be considered.
2. No carrying case
Portable products without carrying case can not be understood, because it is necessary to bring it out of the portable, the equipment out of the bag is not equipped with protection products, this point in the second generation of products that you want to be considered.
3. Too many compromises are not good
I think that such products should be reasonably priced in 1999, based on the price to make products, then either from the hardware configuration or material details can be enough effort, with the ability to do low prices in the future is also possible, this The first generation of products feels like going down the price line, because the price is a lot to choose from, from the above panel and touch can see sincerity, but with the accessories and the bottom, I feel abandoned based on the price a lot. To tell the truth, these products are always niche products, so considering price factors too much will affect the market with prices. I think at least not yet. I hope to see the second generation of 1999 products with high configuration, sandwich structure and complete accessories as soon as possible.
