I used Ace for two showers in my brand new home. After the initial installation I did have some discoloring from the glue or something that they used around the brackets. They came back fixed one at my home, took the other and returned the following day and installed it.
I could not believe the customer service. I have recommended them to multiple people. I highly recommend you use them as well! Its very clean looking in my modern home.
