Review on Xiaomi Mi Smart Compact Projector: Full HD Resolution, Portable Home Theater, 500 ANSI Lumens, Sealed Optical System & Integrated Sound Chamber by Michael Tegan

I was so excited to get this projector as it combines everything I currently have (projector, mi box, speakers) in one device. , Mi Projector. All reviews mention good picture quality, sound quality, etc. After using the device for a few days, I noticed that the image quality became fuzzy/blurry for about 30 minutes after turning on the projector. When the projector is turned on, it performs an auto focus function which makes the image very sharp/focused. But after running it for about 30 minutes, the image becomes fuzzy/blurry. Not sure what is causing this (motor/lenses extended?). Running focus from a take will bring the image back into focus, but it's actually wrong. Disabling the autofocus doesn't help either. I am contacting Revain to send a replacement and will see what happens. Update: The replacement device has the exact same problem. After about 30 minutes of running time, the image becomes blurred. There is no choice, you have to send it back. I contacted Mi Support regarding this, they asked a few questions which I answered and no more feedback on the solution.
