This thing is awesome, 300 lumens is a killer feature on this product, and it shows how powerful even a small and portable projector like this can be. It's even as flexible as some of the big units can be, this projector has pretty much any input I'd need, even some that I don't need!
I bought this to use on business trips, and it's served me quite well on those, it performs well under any condition I've thrown at it (dimly lit room, lots of people, etc) and it handled them all quite well.
