As described levelling system for tiles they worked but the metal support that goes under tiles to level could be longer so gaps between tiles bigger. Some were not so easy to remove once adhesive had gone solid . Easy to adjust height and level of tiles with a simple twist of plastic holder overall ok

The product came quickly, the seller completed as a gift 3 drills on the tile, it would not be bad if still in the kit sent metal pads for fastening)

It is accurate, except there is 0 of the 2 pcs of orange keys present…Hope it will work, delivered on time.

It's all is well. The product received, meets the description. Thanks to the seller.

What you need. It all came as a description. After work I will add a review.
