Summary: Great LITTLE projector - good for trips - hotel room, small office, kid's bedroom. I chose it for its 3D capability. With a 50" projection, 2D is fine, but 3D is barely bright enough because of the glasses. Still we have enjoyed the 3D movies we played through it.
Summary: So i got this projector a few weeks ago and so far i've been impressed by it. The seller actually sent me the non-lite version but i haven't used the extra features yet. Things i liked about the projector: price and image quality.
Summary: Bought in 2011. Have some problems with flow focus(stabilize after heating 6-10min), noise(just for quite films and small room), plastic optics(for this price they can use normal glass). But for 400$ it's my best money spend.
Summary: So the video is great and aside from the other issues like, the volume playing from the device and the carrying case not being shipped with the projector as advertized. I have no idea how to work the 3d mode.
Summary: For a dark room, this little projector works great! I would recommend getting the Q5 with 500 lumens if you have that extra cash, but the Q2 works fine for what we use it for. Best part is running files, movies, music videos, all from a usb. No laptop needed to be connected.
Summary: In a nutshell this projector looks identical to the original Vivitek Qumi Q2 (now end of line) cheaper and has a significantly higher contrast ratio of 10,000:1 instead of 2,500:1 so its ideal for watching movies.
Summary: I have only had the product for one day, but my first impressions are that this is a well made quality product. The build quality is excellent, perhaps not quite Apple's "object of desire" quality, but certainly a cut above most consumer products out there.
Summary: UPDATED 7/21/13: The projector itself is very nice, producing a sharp and visually pleasing image for PowerPoints and movies. My beef is with the specifications, which clearly state this device has a built in, 1W mono speaker.
