don't buy those, not only has the frame now more gap from the wall, it also has a visible red-lit receiver tooth on the bottom right. So it's quite obvious this is a TV not a picture frame. The pictures cost 5e/month subscription and the software is so slow and buggy it's just sad.
oh and when your TV crashes, there is no reset or turn-off button, you actually have to pull the plug - which, considering it happens often and the TV is usually installed in a "hide-away" manner, is really annoying.
