### ⭐⭐⭐⭐⭐ So far so good
*by B***. on January 2, 2020*

Building a shower with 2 niches, I’ve used these products several times, so far so good

### ⭐⭐⭐⭐⭐ Love the Kerdi system!
*by A***R on September 19, 2024*

So I order these off Amazon because they are a great value. The installation of the waterproofing system is not complete without the corners and these save me 1/2 the price.

### ⭐⭐⭐⭐⭐ The real deal and passed flood test
*by L***C on October 18, 2022*

So use the real deal Schluter corners and not the knock off no name brands. The extra money keeps you warranty with Schluter intact. Use their products and follow their online instructions (DIY), or pros go get certified. It is worth the money to use the real stuff not the knock off brands you will find on Amazon for half the price. I used their products, followed the instructions and passed my 24hr flood test with no issues at all.
