Query: Poor quality. No Warranty.

I bought 2 of these. At least one or more of the connectors in the wall plate did not connect properly with my HDMI cable. So I got intermittent failures. I tried replacing everything, but the wall plate. assuming it was something else. Very costly mistake. Turns out it was the plate. And cannot return for replacement. No warranty, apparently.
