We installed Traffic Master 12"x12" stick down tiles 10 years ago, in what was supposed to be a temporary fix until we could do ceramic. They still look great - have not lifted, shifted, discolored, etc. We've left them, because they are working well, and why replace them? The only thing I would change is I laid them butted together, not grouted. I was too timid back then to attempt grouting. A few years ago, I used a different brand in our basement bathroom, but went ahead and grouted them. They look great, and everyone thinks they are real tile. Grouting is the way to go.
