We purchased 25 of these mats for our home gym. They are heavy, very durable and handle the gym activities very well, unlike the foam mats we had in there previously. They cut easily with a straightedge and a regular razor. These mats may be slightly off in size here and there but to account for that just lay the mats in a broken joint pattern, like a brick wall and you will be fine. One other tip is to either use black paint or stain and paint/stain the subfloor anywhere a border of the mat will be so the subfloor won't be seen if there is a gap between the mats.

I bought 3 of these over the summer for my dog kennel. These are recycled material and do not hold up. Took them out to clean and two of them split in half. I would recommend spend the extra $ and get the higher quality ones
