Got the shell bought because the steering wheel is very worn out by my car. The casing could be drawn without problems with some Kraf over the steering wheel. I only did not pay attention, they symmetisch pull on the steering wheel. Therefore, I had to pull them off again, what was a little hard. But so shall it be so. ;) Did the shell then moved symmetrically over the steering wheel and it is locked.
Coating feels good, and is seated at hot days not so warm (at least the red part). ---> Buy recommendation
