What can you say about samples? Well, I can say is that the material felt stronger than comparable Karastan materials. I did not find another flooring material with a thicker "wear layer" at 40mm than Flooret - others typically fall into the 6mm to 20mm range. With ordering multiple samples we felt like we were able to evaluate the locking feature of the samples. Everything connected nicely. We found a small sample we liked so then ordered a large plank. I recommend this before the final purchase so you can see the material in various light conditions. Flooret customer service has been exceptional. I referred my brother to Flooret for his project and he liked what he saw so he is purchasing 500 square feet. Shipping from WA to FL works out to about $.40 cents a square foot - seems fair in today's economic conditions. Assuming you find the color and texture you like, the flooring material in the Signature series appears to be a good value. Good job Flooret!
