Yaber u11 projector is a nightmare to use

Yaber u11 projector is an absolute nightmare. I bought it on 60% Sale - now I understand why it's on sale. Not user friendly and does not deliver on the features advertised. The USB ports don't work at all. It doesn't even show them as an option to choose although it's advertised as being able to connect USB. Netflix is a nightmare to instal. After I finally got it to work, it stopped working because of a new update. When I try to instal the new update it freezes. Uninstalling the App and reinstalling doesn't help. Rebooting the projector doesn't help. I would return it and buy another brand but the whole experience has completely put me off of projectors.
