My first time using leveling clips. They were a life saver. Leveled everything out even with uneven subfloor and 15”x30” porcelain tile. I was skeptical with the price and several bad reviews but I would absolutely buy again. I bought two kits of 1/16” because I have two big bathrooms to do and was thankful I did because having two of the squeeze clamp things set to two different sizes was awesome. For the heavy lifts, you need all the jaw space you can get to start the shim, then you switch to the other tool to really put the squeeze on. Could have just adjusted the one each time but ain’t nobody got time fo dat!I only broke one clip on the squeeze. The rest took a shocking amount of pressure and actually deformed without breaking.I only had a handful on the job not break off clean under the tile and they were pretty obviously all my fault. Be careful not to let mortar build up around the spacer base, otherwise that will “reinforce” them and break above the surface. Most of the time a pair of dikes would pull them right out, but a couple I had to use a carbide blade on the multi tool to grind below the final grout surface.Overall very happy with the kit and the price.Shims are rather cheap looking but worked just fine. I don’t expect them to last more than a few tile jobs... Tools are built cheap and flex weird and squeeze crooked, but it did the job just fine and I have confidence they will continue to perform on my future jobs.Upshot -It’s a good system and if you use some intelligence on how “things” work in this world you won’t have any issues! Save some money and buy these!P.S. There were all the same type of bad reviews on all the high end leveling systems too so it’s pretty obviously user error.
