The only problem is that quite quickly it slide less tied to sweating / oily and other waste that end up on the carpet. We must therefore wash it once with a little dishwashing liquid to recover a sliding resembling early without recover the original feelings.
After a year and a half my stack began to slightly curled at the edges so I have bought a new one. I must say that my use is intensive. But I really recommend this carpet is still very pleasant level of skiing!
