I have research for a while for the best Pico Projector right now . after see all the trust review -lrb- TechCrunch , PC World , etc -rrb- I think this would be the brightest Pico projector with the most functionality . I be one of those guy that may not ever use all the option on a device , but like to have that option available if ever the time for it come up . the p4 do not disappoint , for something so little , it be very bright . I be surprise to see how bright this thing be ! I use it to connect to my lap top and watch movie because I tend to travel a lot and watch with friend . they all love it too . the one thing that be a minor annoyance be the fan , but if you be watch a movie with the speaker on , it be not so bad . I would recommend this to a friend .
