You mean the stuff that comes in rolls? (Tarkett Fiberfloor is one kind) I got some about 10 years ago and absolutely love it. Went to find more recently and was very disappointed to find that it's no longer available (!?).
Here are the pluses and minuses:
Plus: it is somewhat cushiony, tempers the cold of the floor, and is absolutely smooth (easy to clean).
Minus: It is not the most durable--it does get dings. But I've had mine in the kitchen for 10 years and it's in good shape.
