Review on BEAUTYOVO Interlocking Foam Gym Mats - Puzzle Exercise Mat With 12/24 Tiles, 24'' X 24'' EVA Foam Floor Tiles For Protective Flooring, Ideal For Gym Equipment by Alan Miller

These mats seem to get the job done if you need something in place temporarily or cannot afford higher quality. Surprisingly durable for how cheap they are. But they do feel cheap and constantly shift around. They do not stay locked so if you move around or move equipment around on them, they come apart easily or will buckle like a rug. If you just need something to go under a stationary piece of equipment, these are good. If you want something to workout on, recommend spending extra. I got these for a temporary space to workout before I move, but will spring for higher quality after I move.
