These shelves have become my terrible addiction. They are so easy to install, I want them EVERYWHERE! I tried to get my wife to install one just to make sure they were as easy to install as I thought they would be. Of course, I'm a big guy, and even I had trouble pushing the fasteners all the way into the wall. But every time I got stuck, I'd just grab a hammer, rubber mallet, or book and just push on the raised edge of the device. The 8-10 shelves I bought never had to be hammered. My only complaint is that I can't buy a bigger, deeper shelf. I understand the design limitations and why the shelves are flat for light weight. But a guy can wish for it, right?
