## Customer Reviews

### ⭐⭐⭐⭐⭐ Approved
*by K***M on March 12, 2025*

Perfect for our shower install, great product

### ⭐⭐⭐⭐⭐ Nicely made and great time saver
*by T***S on August 31, 2022*

This is a nice easy to use product. I actually liked the Wedi better, but this was okay too. It is a little thinner than the Wedi, which is much closer to a half inch. I would put this at about 0.43 of an inch, like "1/2" tilebacker hardi board, so it goes well with that product (which is like 0.42 of an inch)

### ⭐⭐⭐⭐⭐ Brilliant
*by A***A on February 3, 2024*

Extreme simple to install. I like it
