I've been in the carpentry business for more than thirty years and this was the worst product I have ever dealt with. Installing it so it would lie flat AND stay together was nearly impossible.
It got to a point that it looked like a cartoon, with me getting them flat in one area and another section would pop up.
In the course of going back over and over, a lot of the edges started snapping off.
Obviously, this *** was going back to the store.
To my amazement, I was told that since the product was "installed" it was not returnable!
The worst store, the worst products and now it turns out they were the best at one thing: Lying to their customers, putting who knows how many infants in danger from crawling around their shiny new formaldehyde infused flooring.
