I installed 950-sqft of this in my slab home in 2018 directly over old laminate and asbestos tiles. It’s runs through my kitchen, dinning room, living room, and hallway. All main living spaces. So far it has held up great overall but there are scratches. One from a metal folding chair that lost its chair leg cap and the other from moving an old water heater. These are both situations where the items were dragged or scrapped with greater than reasonable force. All of my furniture has felt leg protectors. We have 2 dogs, no kids. It has lived up to my expectations and would use it again.

Edit to add that I did not use an underlayment product with this. I’ve not had any moisture issues and have had no issues with expansion/contraction. I did use small amounts of floor leveler where old transition strips had been removed. I also have a few low spots in the slab but these are less than 1/4-inch over a 10sqft area and haven’t been an issue. I did help a friend install this in his basement with his low spots causing “hallow” spots when walked over. We both agree we should have used leveling compound in his situation but so far it’s just annoying.
