I don't have any experience in having one but I ordered some samples from an on-line co. I ordered 2 of the grayest plainest ones I could get & they were really ugly. I was expecting ugly but was trying to keep an open mind because of the good qualities of the floor. I ended up getting a ceramic looking vinyl tile & I'm really happy with it.
I don't have one but my neighbor does and it is stained terribly. She does have 3 kids and perhaps it needed to be sealed but it looks like a stained bulletin board on the floor.
