Review on Gym Flooring Tiles 12/24/48 Pack - Exercise Mats For Home Gym Equipment, Garage Workout Mat Foam Flooring by John Shorter

Update: The seller stated that they had changed to a newer version and that amazon had a mixed inventory. After working with the seller, I was sent the correct version of the tiles which do now match. The mats are fine, especially for the price point. I do notice that they can deform under weight and stay that way. However, this is minor given the price. Updated the review to reflect these changes.I ordered 24 tiles first and found that I needed more to finish the room. So I just ordered a 12 set tile of the same Black and Gray. The second set came and the texture is softer and smoother with less grip. The Gray tiles are slightly darker and the Black tiles are much more gray. I did notice until I added them to the mix and it was night and day how different these are. It looks like they switched manufacturing process mid way though and the next set I received were a slightly cheaper product. I don't have much I can do either since I have the whole gym set up on the first set and the next was just to finish out a portion of the room. So I can't exactly dismantle and entire rack set to get these up and send them back. So 1 star it is. From the pictures you can see the Black on Black where the new black tiles look nothing like the old black or gray. The new gray tiles are harder to tell by the picture but are quite different. I order these just a couple weeks apart from each other.
