It is easy to use and works as advertised. This is ideal for use on a drywall. It is NOT designed for outlets. My use was to install ethernet ports for use through the wall and I didn't want to go through the hassle of finding a stud and installing a suitable gear box. My local hardware store didn't have this product, but did have a sheet metal version with two "sheets" that needed to be folded in to hold the product in place. Far inferior to that. I bought extra to be "in stock" after my original purchase. They close tightly and the covers fit perfectly.
