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

I use this to do Tracy Anderson workouts which are a mix of cardio and weight exercises where you may be lying down or on your knees.The good:- does not move around on wood floor while doing weight exercises that do not have much movement- VERY comfortable cushioning for knees and wrists, lying down. Absolutely no knee pain. I do not need a separate mat to cushion my joints. I have tossed hand weights (note: less than 10 lbs) and worked out with a kind of heavy folding chair on these tiles and there was no damage to the tiles or even denting.- Easy to clean- good durability (I also roll my office chair onto some pieces as a floor protector and it holds up!)- no smell, does not absorb smell of sweat- hair does not stick to the floor (easy to clean up/vacuum)- good grip even when your hands are sweaty- floor absorbs sweat wellThe bad:- The tiles do slightly slide on hardwood floor when doing exercises that have more force and movement, like if you do a lunge and then quickly switch positions laterally- I did not need to glue any of the tiles together initially, but after about 6 weeks, I had to glue a single which had begun to expand away from other pieces due to frequently pushing down on that tile away from others (like doing a downward dog type of position, where you have opposing forces). The tile's pieces no longer quite matched up due to having stretched away. Eventually I had to glue together some other pieces. In about two months, I glued together 4 pieces in different positions. They were not damaged at all, but they had just started to kind of extend away from other pieces due to pushing down on them.- If your feet catch out the connecting seams of the puzzle pieces during a quick movement, you will push up some of the puzzle seams and this can be distracting- the pieces that come with the tiles to cover the edges do not allow you to necessarily do so seamlessly all the way around the edge. Some pieces need to be cut to fit against edges of another tile. Some other reviewers mention this. This is a cosmetic problem that is easily fixed, but mildly irritating.Do I regret buying this? No. I do not regret buying this because it gave me the chance to try my workout on a much larger surface area for a low investment (rather than be limited to a small regular exercise mat)Will I replace this with a solid piece of exercise flooring (like a large exercise mat)? Yes. This will also be way, way more expensive but I am prepared to do it after having used this for a over 2 months successfully. I just hate when my feet catch the puzzle seams.
