this thing be amazing ! great resolution , compact and excellent build quality . the on-screen menu and micro sd slot be all welcome addition . I put on a episode of top Gear in HD on it and another officer on my ship watch comment its as good as he flat screen at home . my only complaint be the lack of ipod adapter , extra battery -lrb- both of which come with the pk101 -rrb- and the video encode software . the software take a 600mb . mp4 file -lrb- that the projector say be not support -rrb- and increase it to 1.4 gb ! I recommend use HandBrake -lrb- it be free -rrb- , use the iPhone setting and bump the resolution to around 640x352 -lrb- what I have the tg episode play at -rrb- . aside from that , I be very happy with this projector .
