I received the kit timely and buying by the kit saves money. As a DIY’er this was my first time to lay Travertine floor tiles. The levelers are incredible. They work great to keep the tiles level. They break off easy after the tiles are set without damaging the stone Travertine. I would recommended getting the pliers to push the clips in. I pushed a few in by hand and then used the pliers to check them. You can get them much tighter with the pliers and you can also adjust the pliers where each clip is the same tightness. Great product and I would highly recommend it.
