The Yantra Mat is a real challenge to reduce stress to begin with. After repeated use, the body and mind is more and more a fact and the success shows only really the effect. I groped me very slowly and had to drop out of one or the other times. For quality can still say that all plastic plates are complete and in good attachment. The mat is quickly rolled up and stowed class in your pocket. The seams act firmly, stability and size are perfectly adequate for my use.
