There are much more expensive systems out there, but I doubt that they surpass the quality of this American Standard system. Solidly built, most components were metal, installation was very easy and after 3 months of use we are extremely pleased. I was/am hesitant about drilling into the wall tile so we used the double sided tape to connect the lower portion to the tile. I really wanted to make sure that this was the unit for us so I didn't want to drill holes for something that I would have to return. So far the tape has worked really well, if the tape does fail I will likely try an adhesive before drilling holes but so far so good.
