These shelves have become my terrible addiction. They are so simple to install, I want them EVERYWHERE!I tried to get my wife to install one just to make sure they are as easy as I think they are to install.Of course I'm a big guy and even i had trouble pushing the hardware all the way into the wall, however every time i got stuck i would just take a hammer, rubber mallet or book and just press on the raised edge of the hardware the actual hammer hit was Never required on the 8-10 Shelves I've bought My only complaint is that I can't buy a deeper shelf I understand the design limitations and why the shelves are flat with little load capacity ability are. But a guy can wish for it, right?
