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: I highly recommend that you do not buy from this seller : COMPZILLA Their advertisement for this product is very misleading. When i received the projector, it did not include the two hdmi cables or the carry pouch and most importantly the USB does not function on this model. (Its a service only connection).
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.
Summary: This is my first projector and i'll never go back to a regular tv. I wasn't sure if 300 lumens would be enough, but with blackout curtains it looks good. Blacks levels are only acceptable in a completely dark room. As ambient light and image size increases, the image quality decreases. I'm projecting a 100 inch image with no issues. 3D only works when using the VGA connection and a PC with compatible graphics card. The Qumi only accepts 1280x720 and 1024x768 at 120hz.
