Lumiere White Marble Effect Large Polished Porcelain Tile

We have had tiles before from tile mountain and was very pleased so just moved home an thought would stick with what we know they didn't have same floor tiles as we last used so we got larger more expensive ones started to lay them today and 2 chipped on manufacture edge from a plastic self levelling clip very disappointed as cheaper tiles we have used was really robust kids dropped all kinds not even a scratch and these have chipped on install from a peace of plastic we have now lost confidence in how long this product will last and now need to repair 2 tiles before even finished the floor just disappointed more expensive is not always better I suppose
