Magnets seem strong enough but I can never trust magnets alone when hanging my new Apple TV 4K 6ft above concrete so I used duct tape as a uses a safety reserve if the magnets slip. I attached it to the back of the TV using lots of metal to hold it in place, but be careful a lot of TVs are plastic and don't have metal to use with magnets. In any case, the thing is neat and clean and looks nice. Time will tell if it holds up.
