The mat is not bad, the Halbarkeit is very questionable

The material thickness is more unangehnem for use on hard floors, with me stoneware, just enough and on time.
After unpacking from the box and the film falls first on the strong smell, which quickly evaporates, but immediately reappears when occurring moisture. Unfortunately, this is also due at the most competitive products of the case and on the plasticizer used.

After now now 20 training sessions of 60 minutes, I notice, however, that the mat gets at the surface inlets and marks that are no longer disappear. It looks as if the foam is not stable.
I train without shoes and any device with only your own body weight.

As I ordered a parallel mat Sissel which, although almost twice as expensive, but not exhales, is thicker and more stable, I'll probably use the gorilla just as emergency kit on the go. Since the lower weight makes bemerktbar.

For the regular workout at home, so a maximum of 3 times a week, it may go. With daily intensive use wirds problematic.
In extreme contortions the mat mE is overloaded. Therefore, it is not recommended for gymnastic exercises, but perfectly usable as a sleeping pad.

I would not buy again ...
