Was installed in my kitchen 3 years ago by a professional from Carpet Factory Outlet in Cheektowaga NY. It is not grouted so a sealant was applied between tiles. The sealant is starting to pull apart. Therefore dirt is trapped between tiles and looks very dirty. Also, the floor chips very easily. For what I paid I could have purchased hard wood flooring. I have ceramic tile that is 26 years old in my foyer and it's beautiful. I have pergo flooring in my dining and it's 12 years old and it's beautiful. I have hardwood in my den and it's beautiful. I wish I could post pictures so you could see for yourself.
