It has been sufficiently fine for what we were looking for, the image shines acceptably in medium dark light, obviously is not a heavy duty projector but it works fine for home and personal entertainment and some job quick duties. Ideal for watching pictures, music videos and movies, and by the way we were delighted when we finally found a video format that the device was capable to read (MPEG-I 352x240) of course is not HD as the technology would need to improve a lot to reach blu-ray definition capacity in such a small device. Audio output connected to small amplifier speakers sounds well. Yes, we needed to find a video converter online, we found a lot of them for free at [....] . It runs out of battery pretty fast though, besides it can work with a DC adapter plugged in. Careful usage is a must, chinese devices are like a hair made of gold, it can long last for ever but are as delicate as a thin hair. We hope it would last long time as this is just barely the second day we use it and so far so good...
