1. Corners can't be focused no matter what. Focus wheel works just for the center image area which is approx. 50% of what you'll see. The rest will be blurred. 2. "Design allowable error +/-8%" when it comes to the geometry distortion. That is real and quite a clearly visible distortion. 3. No matter what is the marketed contrast ratio, the printed spec says 800:1 and, again, that will be your reality. However, even that would be acceptable but corners have a way lower contrast than the center. 4. Crappy DHL took two weeks to deliver within Europe and costed some 17 euros. That is not related to the product itself but just FYI. Summary: I didn't expect miracles from the cheap projector but there are definitely much better alternatives available for the price range.
I ordered it from Czech republic to Denmark. It arrived in about 5 days. It was sent from Germany, so no need to pay additional taxes ! I used just for 1 evening and here is my first impression. Pros: FullHD, price, built-in video player (I have basic ver) cons: you can hear its fan from 4m in normally quite room; focus either in the center of the picture or off the center, at least in my setup (4m till while wall) Other than this it is a good product. worth its money!
