### ⭐⭐⭐ 







  
  
    This is NOT Schluter KERDI.  This is Made in China knock off!!
  

*by M***W on Reviewed in the United States on 25 October 2021*

I should have looked closer.  The description images are so close that I thought this was a great deal on Kerdi membrane.  The installation images even show a dude clearly installing KERDI brand products, but this is a made in China knock off.  This stuff might work fine, but why risk tens of thousands of dollars in repairs from a leaking shower??  I am returning and ordering some Schluter KERDI.  Another $50 is way better than rotten framing and mold down the road.  I give three stars because it looks like it would probably function like other membranes

### ⭐⭐⭐⭐ 







  
  
    Not clean as Kerdi but definitely good
  

*by M***O on Reviewed in the United States on 26 March 2022*

It works as advertised

### ⭐⭐⭐⭐⭐ 







  
  
    Easy and effective
  

*by T***N on Reviewed in the United States on 28 December 2021*

Product as described.  Hardware store quality at a better price.  Smart to add this to your bathroom or other wet work.
