This projector video is amazing! If you are looking to not ruin you in a video projector, if you want to impress your children, they are not too demanding to mili millimeters how some adults, you have to be really demanding compared to HD quality (how some people) to be bothered with quality diagonal 2.5m (already large). The kids love in the darkness of the night was a cinema at home for them. Listed sound integrated speakers are sufficient to children, but for adults it is more disturbing. The side is incredible portability, lightweight, can bring by all. Next operating system, it is nickel !!! Android adapted, I connected a disk 2 Tb navigation was easy, it supports very well the files to mkv. Advanced and retreated rapid film. Listed Wifi, impecable! I could watch movies stored on my NAS media server. The Battery, I think a small can, but I connect it to watch movies (for me the battery lasted 1 hour max) I use a cheap and foldable tripod. It would have been great to have a backlit remote control, but hey you can not have everything ... by cons you can download the Android app that you can use in place of the remote control!
