When price and size considering an amazing device

Anticipation noted: We should not expect miracles. Selbstverständlilch the projector is limited by its small size and very low price. The offered functions can be realsieren because only by compromising on quality in detail. I try therefore to objectively evaluate the performance of these considerations in mind ...
I had some bad luck, but I am fussy and had only two Faulty devices in front of me (even image badly, once loose battery) ... but that seems to be a general problem, otherwise would probably often criticized here ... In any event, I checked as 3 projectors through its paces ... and now I'm happy ...

Good:
+ Height, weight and body really allow the projector take anywhere
+ The full equipment with an integrated media player, battery and speaker allows just in case absolutely autonomous operation
+ Functionality as Power Bank for charging other devices is traveling extremely useful, taking the projector so also if not at "plans" to start using it, simply because of this function, and would be then when it's there when it comes to unforeseen use comes
+ In otherwise dark rooms can be absolutely respectable image sizes of up to about 1.80 m image width realize
+ The Projetionsverhältnis is good to throw for example, from the bedside table of a picture on the bedroom ceiling if you like in bed watching movies etc.
+ The built-in media player plays almost all formats from, but with restrictions, more on this below
+ The built-in media player has an amazing variety of functions: aspect ratio, audio tracks, subtitles, playback speed, pre - and rewind, forward and forward navigation through files in the folder, Zoom, Repeat, AB Repeat, information on the codec etc, unfortunately, a two bugs, this down more
+ The connection options leave nothing to be desired
+ The intelligent solution with a separate USB for charging and for use as a power bank means you need only 1 USB cable, it is only turned for loading / unloading
+ Micro-USB is today in almost all telephones standard (sorry Apple), so you have to take only one cable, super
+ An inserted micro SD card is flush with the housing. So it is not lost, remains nowhere hang and if you choose 32 GB, fits an entire collection of movies and series on it, great for trips and excursions !!!
+ An amazing setting variety, it can be the image orientation, color temperature (also manually), brightness, contrast, sharpness, transparency of the on-screen menus, language, highs and lows of the sound, Lautsärke etc. Setting, below are the in my opinion best settings
+ Once adjusted and properly aligned, the image amazingly sharp, so I did not expect
+ Color reproduction is amazing, and powerful, even so I did not expect (after adjustment)
+ The aluminum housing acts valuable and robust
+ Pleasing lightweight
+ The resolution is quite high for pico projectors, DLP devices are often under or are considerably more expensive
+ The 4 LEDs on the bottom indicate the charge state that is not even in the product description and is very useful
+ Operation is almost silent, only a very very faint humming sound is when you walk a few cm

You have to accept (due to price and size):
~ The light output is too low to project in a non-least dim environment usable images that are larger than A4
~ The resolution is sufficient to watch videos and view pictures, text images are very grainy and no joy, even holiday course to lose brilliance ... for clarification, the picture has a quarter of the resolution of Full HD and is approximately as dissolved as the lowest setting that you can then use the PC today ... because you realize how pixelated it is, it does not fall when watching movies but for free !!!
~ The internal speaker is really only a temporary solution, but louder than many mobile speakers ... with the headphone jack, but can connect headphones or speakers, the levels are high and allow surprise a very loud sound
~ The focus wheel is small and fiddly, you need a bit of practice until you get the hang has ... Anyway, I'm not of the opinion that the position at the bottom is a huge problem ... as long as one to the projector at the same distance holding projection is focused precisely in his hand and then puts it away again .... now is not so big problem
~ The media player plays a lot more media formats specified as Aiptek, but it can cause some files lead to a delay in the audio playback, I appreciate about 0.2 seconds enough in any case that it is no longer fun. I have taken in this regard to Aiptek Support Contact and have to get the opinions here connect, support is super friendly and knowledgeable. The answer to the problem is sobering, the certification of formats such as DivX, MKV etc etc will cost considerable royalties ... and that would have exceeded the cost estimate. Therefore, these formats are unofficially supported and not correctly reproduced precisely in some cases. Because that is not foreseeable, these formats are not specified in the description. I think that is understandable and fair ... although I would have gladly paid 5 euros more for full support. At the bottom I have listed what works for me so far and what is not.
~ The buttons are poorly finished and look cheap, but the pressure point is more than clear ... here there were significant differences between the 3 devices ... the last time the keys were stuck in the housing, with the first two, they each had some play
~ The battery life of something around the 70-100 minutes is a bit short, a few more would be enough mA for a complete feature film, it is sufficient only for some shorter films or series
~ The brightness distribution is good enough, if care is taken, but the upper left corner is often a little darker ...
~ All devices have color clouds, sometimes more, sometimes less. The first device was a bit disturbing, the other two do not. For color images that is hardly noticeable, in black and white shots then something ... I can live with that ...
~ There is no lens cover, I would always carry the projector in a sock or better as a protective pouch

That should not have been:
Been the slideshow stutters quite at the image transitions that are too animated ... without animation Währe the better -
- The animation in the music reproduction is useless, but it lit me not a why you should use the projector at all this unless you have the music not etc on the phone ... the speakers are in any case no argument
- If you change the media player the aspect ratio, this sometimes forgets the set audio and subtitle track, not always
- You jump to the next track, the Media Player will switch back to the previous still image aspect ratio and to the first audio and subtitle tracks, annoying if you look, for example, the series all have the same aspect ratio
- When connected to the computer, the resolution turns out to be somewhat problematic because of Windows does not recognize. It has the best record at 720p, so HD Ready ... but then you have a significant overscan and loses all round quite a bit of image information ... for clarity, it is about half the taskbar cut ... this edge is then peripherally. However, that falls in videos not in Windows and display of presentations not ideal ...
- The image factory setting is abysmal ... more on this below

Among the video formats (in all formats, sound and subtitles were provided choose a selection existed):
+ Definitely run the videos that are specified by Aiptek
+ DVD files (untouched)
+ Full HD and lower container in MKV format, AVI (all I've ever tested)
+ MP4 in MP4 container
+ FLV
~ DivX videos in AVI containers run about 95%, but the sound is at about 50% asynchronously. There is no connection with the bit rate or resolution, some flaps, some are not

All in all I am impressed that even Full HD material runs smoothly. If you know about the limitations, you can choose according to ...

To adjust the image:
Factory the image is too bright and black areas of the image appear gray, the image is very blurred. It is also very easy green / blue fusty. This was the case for all devices.
For me, the image is much better, if you set the brightness to 46. This value was ideal for me with all 3 devices. Of course, there may be differences as. I would recommend to choose a dark scene and then adjust. It is then immediately clear because any change equal quite strongly influenced the image ... The setting is made for each source separately !!! Ditto for the color ...

CONCLUSION:
For this price a good performance. Definitely a really Distractions device that when used correctly, is ideal for travel and wherever you do not have sufficiently large TV or want to watch with friends or video games. Can output the HDMI In Verbidung with a loudspeaker and a mobile phone there is a travel home theater or entertainment center for all erstaunenede convivial evening demonstration of YouTube or scheduled by any quiz apps etc etc
But it must at the price and the size should not expect miracles and after purchase check carefully whether the projector is processed properly.
