I've had this mat since 2020 and it's still as amazing as the day I purchased it. I went with the thicker model for knee protection. I'm a bigger girl so stability and grippyness was important to me. I've shopped around and had many mats before my BMat but have not found anything that compares to this one.The quality is great, it's easy to clean and it's super grippy!! I give it a deep clean 2x a year (see website for instructions) and it comes right back to its former perfectness, except it get more supple with each soak.The only downside is it has a strong rubber scent at first but wears off after a couple rinses. Others seem to think it smells like chemicals, but it's 100% rubber so I don't know what else you'd expect from the mat.
