it's just a pocket size 1080P projector with 4 hours of battery and also Harman Kardon speakers.
Good price for that model, sells HK $8000 in HK, around AU $1400
now half price at $650 with eBay Plus.
300 ansi is a minus, not bright enough for outdoor use.
200 units in total.
with Android TV, not some scary customised system, so pretty handy.
