I've been doing Yoga for over 2 years now and I have my own class. I have owned 15 different sets and brands of yoga mats now and I can tell the difference when it comes to quality and durability. For quality wise, I will definitely rate this mat A+, it may be inexpensive compare to other popular branded yoga mat but they just actually have the same quality and specs, it gives me a great grip even if it gets wet due to sweat and it does not slip. Also the best thing about this mat is that, it does not make a rubber squeaky sound. When it comes to Durability, I still rate it A+, I have tried all pose I learned on it and it's still on it's perfect and brand new shape. I am very impressed!
