I have been using this mat for few days now and turns out to be quite good for the price I paid. I did read few reviews before my purchase about the surface coming off, however I feel the surface of this mat or any other foam mat would only come off if one keeps the toe nails sharp or long. While doing yoga I have had good grip, comfort and no issues with the overall product quality. It's as good as any high brand mat. This one comes with a bag, so that was another positive add-on.One recommendation is always go for a 6 mm mat for any kind of workout especially yoga. Thicker mats don't serve the purpose.
