Summary: If you need a bright battery powered projector this is the best on the market. I was worried it would be very cheaply made, but it says 65% USA parts. Keep in mind that on battery mode it projects at 160 LM, .. the 300 is when plugged in. The battery last for a full hour, but not much more. I use this to show 45 min health care videos in the Amazon Jungle. The other thing I was worried about is it heating up and shutting down like other projectors I have had.
