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. With 2D - good clear image, plenty bright in a darkish room. Needs a 3D adapter to play blu-ray 3D movies.
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. The picture really looks HD and i think at this price point this is the only projector with a native 720p resolution. You do need to have the room pretty much 85% dark though, so i mainly use it at night time.
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. I explored the menu and when i came to an option that had to do with 3d i realized I can't do anything so now I have a lot of 3d movies a 3d player and the projector isn't recognized as 3d. How do I fix this?
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. The only drawback is it's a plug-in power adapter so it's not wireless.
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. To get the price down Vivitek have simply removed a few of the original Qumi Q2 features such as, the ability to stream via a wifi dongle and connect to a 50 lumen external battery.
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. It is small, light and of course the image is crisp. I also found it to be very quiet, but perhaps when its been running a long time the fan runs faster, don't know that yet.
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. Although the tech support person at Vivitek emphatically stated there is a speaker in this little beastie, I'm only aware of Internet reviewers hearing nothing.
