I purchased this for my home now the installer is very upset due to the difficulty it took to install. I tried to help install it myself and could not get it to "click" as I thought it should. I don't see how it could "click" with a sledge hammer. Installer and I both found it very hard to manage into position to get installed ended up taking weeks to finish, was not worth the trouble it took to install. Please be careful I am sorry that I trusted these glossy reviews and sales gab. Now I am concerned if the claim that it is suitable for high humidity is also not what is I believe that it is claimed to be.
