Review on Enhanced Vivitek Qumi Q2 300 Lumen WXGA HDMI 3D-Ready Pocket DLP Projector (Black) by Alec Winsor

I love this powerful little projector. Image quality is excellent! I've tried multiple connections to the projector. USB flash drive - I've tested a few - A new flash drive works best with a small number of files. I uploaded some movie and PowerPoint files. Both seem to work fine. I attached my trusty Sandisk backup that I bought about a year ago with a few files. not recognized that I have files. I took out the micro SD card from the Android phone and I could see files and folders. I was able to view Office documents (but PDFs would not open). I was also able to view videos, music, etc. from this device. HDMI Connections I had problems with two Android smartphones I tested (no iPhone), the problem was that you had to plug the device in before you started, if you plug it in after you turned on the projector it would go into search mode and the device is not taken. I projected an image onto a pale yellow office wall with two lights on and could still see the image clearly, thinking it had better lights. The light from the window was still coming in and I still got a great picture. So far, so good. Cons: It's very difficult to reach Vivitek's customer service and when you do, they don't answer the phone.
