I had a very tough time choosing between this mat and Lululemon's mat and I ended up going with this one because of the lifetime guarantee. I can't tell you how grateful I am that my intuition about this mat was correct. It took a little bit of time to break it in but I honestly just left it in my living room for my kids to play on and after a week of that as well as my daily practice, it was ready for me to use without issue. It's heavy, durable, easy to clean, and super comfortable. I am a heavy sweater and I have never slid on this mat. I have even used it in the trunk of my car to stop large boxes/packages from sliding around and it works like a charm. Seriously, I do not baby my mat and it has held up in perfect condition for the entire year that I have owned it. This mat is definitely worth it.
