I decided to update this review because it was written the day after I got the mats. I've now had them for nearly 8 years (4 months shy) and can speak to their durability/longevity.Interesting to read the most recent reviews and most seem to be complaining about rips at the seems. I've HAVE NOT experienced that. The handles did, however, come off of one of the mats (the one I use most) about 10 months in.Summary of use:- I bought 2 so I could use for solo BJJ drills at home- I use one more than the other because I'll sometimes jump rope on it or place under bench when doing DB flies or presses. That last use case is VERY rare, but I have used it like that more than a dozen times.These worked great for the first 6 months. Then, the one that I use for jump rope started to peel. This isn't that nice canvas or heavy duty tarp cover that you'd find in a traditional gymnastics or judo/bjj school. It's like a high density / high impact foam got covered with a very thin layer of latex paint. I've attached 3 pictures of what they look like now.One of the handles did rip completely off inside of a year. I ended up cutting the other off because it was useless at that point.The paint continued to peel off. I doubt it was defective because I wasn't noticing it on the other one, so I switched. Shortly after that other one started to get daily use, it started to peel the same way.I haven't used these all that much for the past few years (definitely not at all for past year) because it's a pain to have to clean up these black paint chips/shreds. THEY GET EVERYWHERE.* I deducted 2 starts from my previous rating.* I wasn't expecting these to last forever.* I was expecting that these would tear and wear down, not for the paint to brittle off within months.* They continue to be great mats for rolling. They continue to be as firm and impact resistant as when I first got them.* Seems (other than those on handles) still look good.* Velcro still works well.* Having to clean up after using these, however, has made me consider throwing these away or donating them.ORIGINAL REVIEW----------------------Before ordering, I read the reviews and noticed some people were complaining about a certain chemical odor...In regards to odor:1) I ordered mine from Cavalier Wholesale.2) Black color.3) Completely odorless.Feedback:Was looking for mats so I could work on ground movement at home, hoping to supplement my BJJ training. Because I saw most other reviews having to do w/ girls and gymnastics, I was a little worried it may not meet my needs: I currently weigh 260lbs and was looking for something that could handle my sprawls, landing on my knees if I fell, or me being thrown by someone else. The specs seemed to be fairly similar to those I've seen at other MMA online stores (at half the price), so I ordered 2 mats.I received the mats last night. I noticed they were very solid when I was taking them out of the box. I wasn't expecting that level of firmness. As soon as I took the 1st one out of the box, I extended it and let myself drop, from a full standing position, straight down to my knees. Felt nothing but mat. I then stood up and let my body fall forward (flat as a board). Again, nothing but mat - was worried that with my weight, I may end up bottoming out and feel the concrete. Not worried anymore.Conclusion: Solid product!
