Review on GOOF PROOF SHOWER SLK-0404 Stinga-Level Standard Starter Kit: Achieve Flawless Shower Installations with Ease by Adam Cooper

This is an extremely handy addition to any tile tool kit. I used to level the first row of tiles for my shower and they couldn't have done better. Saved a lot of time and you don't have to worry about finding a fairly straight bar. The only reason this product didn't get 5 stars is that the yellow rubber parts flex too much and I had to use a spirit level on the yellow part to make sure the two red parts lined up and lined up. However, it's okay.
