once. I loved it, but could never walk in the kitchen with any kind of socks on, especially nylons. My feet were always going out from under me. I damp mopped it everyday and then used a dust mop with Endust. Probably why I couldn't stand up in there.
As clumsy as I am now.....somehow I think I would like to try ceramic. I don't know.....like I said I'm still undecided.
