We've not used it, but we're considering using the "Traditional" line in our home and have some samples so we can chose a color. It's 9mm with a v-groove, and when multiple pieces are locked together, it looks surprisingly like a traditional hardwood floor. The finish is nice & is as durable as any laminate we've looked at - including Pergo Select (their "high" end stuff). So far we're impressed with the samples.
