On one tv, the screws that are supposed to secure the bottom part of the mount are too short and can’t be screwed in unless you use an extra long screwdriver. I wasn’t able to so basically the tv is just hanging from the top part and not secured at the bottom. It’s hard to explain, but imagine the tv is just hooked into a ledge at the top like putting coat hanger on a rack. 


On another tv (I bought two mounts), the screw to attach the mount to the tv is too short and I had to go to the ends of the earth (really, 5 hardware stores) to find the right screw. Huge pain. Wouldn’t recommended.
