This works and seems strong but has a little room for improvement. When picking an outlet, make sure the outlet cover is already flush with the wall (no gaps) or this will make the gaps worse. Also. The design lets the shelf slide down when the weight of a phone is put on it, leaving a gap in the shelf's plate at the bottom. A simple fix of the company adding more of a backing at the top would fix this problem. I have new, standard outlet covers so I imagine many will have this same gaping problem. One star taken off for that. Otherwise, this is a simple but brilliant idea. This is perfect for by the bedside or guest room where people will want to charge phones or other small devices. It could also be used to store keys by a door on an outlet up higher. Again, good idea, but needs one fix. It works as intended just the aesthetic is off a bit with the gap (see photo). Even with this, this power perch outlet shelf is genius and I recommend it!
