Touyinger Android WiFi 3D DLP Video Projector,1280x800 200'' LAN HDMI Home Theater Projector

This projector has its pro's and cons.I'll start with the pro's first;1: it has an excellent image quality2: it has duel usb ports and hdmi ports3: it is wifi compatible4: it can be controlled with android phone with the download app5: it does have auto focus and zoom6: it is a 3d projector and can play 3d from usb or pc(shutter 3d glasses)7: it does have play store installed8: it does have kodi installed (however it's the kodi 15 and I haven't been able to update to the latest version)9: I had a few questions for customer service and they responded with courtesy and positive resolve.Now for the cons;1: Unable to update the firmware or any pre installed apps (the main reason for only a 4 star review)2: Not sure if I might have received a faulty projector or there is no speaker installed.3: No bluetooth installed (however I was able to purchase a bluetooth adapter and it works fine)Overall, I really like the projector. In fact I like the projector so much that I purchased a 2nd unit.***UPDATE ***I have received the second unit and I now know that it does have a speaker installed in the unit. It can get quite loud. I'm still quite impressed with the image and now sound quality of the projector.However, I am still awaiting the replacement for the first unit I bought which has no sound coming from speaker. The seller has not responded to my emails.
