Excellent quality product
Small Garage Gym
These tiles are so satisfying to put together, like a super easy puzzle. Didn't have to cut anything except the plastic wrap. No smell that I could detect --unlike my cheap bumper plates. My (4 tile)x(4 tile) flooring is solidly supporting my 3"x3" 11-gauge steel tube power rack (Sorinex XL) while I do squats, presses, deadlifts, pull-ups, and arm swings (just for fun. No slipping of my rack whatsoever, despite my garage floor having a noticeable but small negative slope leading to the door. The tiles help to reduce noise as well. Love these tiles!
