What a fantastic little unit. Please note: It's not high def, it's not super bright... if that's what you're looking for, you need a bigger unit.Where this one shines is it's ease in setup, portable size, and great (really great) sound.I bought this when I saw it used by someone else in a demo. Companies a, b, and c were giving their presentations. The lull while each vendor set up their projector, ran a power wire, and spent a few minutes correcting the focus and keystone - not to mention the clunkiness of these big projectors, detracted from the products they were presenting, in a negative way. Put simply - in the time it took for setup, we got bored.But one of the presenters whipped out this little thing. Had his presentation already loaded on a usb stick. Simply sat it on the table, and off we went. No power plug, no clunkiness. Aesthetically, this thing perked us all up. The lights needed to be dimmed in order to see it decently.. And sure there are larger units that can give the same features but with brighter light, and less portability- but not at this cost.Before I left the room I was already checking out what this thing was, on Amazon. No regrets.Had the chance to use it this recently for an impromptu showing of Its the Great Pumpkin, Charlie Brown, to entertain the kids at a family party. Picture and more importantly sound quality were excellent. Sound was loud and clear even with chatty kids in a room.Setup was instant, and the kids were enthralled and we were able to set it up tucked out of the way in a room not normally used for movies/etc.. If we had to instead dig out the big projector, stretch an extension cord, find speakers, play around with settings... we wouldn't have bothered, and just would have done something else instead with them.So to be clear - this is NOT a home theater projector. It's not intended to be either. It's a fantastic takealong and great for casual or quick setup use. I liken it to cameras. You've got your DSLR, right? Big, clunky, but takes great pictures. But you don't always want to lug it around. So they make some pretty fantastic pocket-able cameras, too - that take better quality pictures than your phone, but don't require much effort to bring along.
