This was about the only choice we could find on Wayfair that was narrow.  There were lots of others but all of them too wide for the space we wanted to use.  The product is OK, typical flake board with melamine exterior.  The instruction were faulty, however, and we had to resolve it ourselves.  The mounting plate has two holes in it for screws to go through for mounting on the wall on the wall.  But the back plate, when slid into place covers the holes!  We drilled through in order to mount the cabinet.  We also made a simple template for the holes so we could pretrial the holes in the wall, and then find the holes when we held the cabinet up to the wall.  Any, it's done, mounted, and suits our purpose.  So there you go!
