Review on Dockem Koala Wall Mount 2.0: Universal Dock for iPad, Samsung Galaxy Tab/Note, Google Nexus, Microsoft Surface - Damage-Free, Smartphone, Tablet, eReader Holder (Black) by Mark Repp

Agree, it's a really simple concept but they execute it very well. When I installed it I always thought it was too expensive and I could probably assemble it myself for less money until I got to the part where you put the washers. They're designed to fit perfectly in the mounts and come in a variety of sizes so you can get the level of fit you want and feel worthy of the $15 price tag. I also like the fact that they designed the brackets to hide the sticky command tab. As a side note, I've used this on lightly textured walls and haven't had any problems so far. All in all a simple but well executed idea and a good buy.
