with my old car the lettering of the key had been tapped for some time. To prevent this from happening in my new, I have gained this cover. Very possitiv me has surprised the good workmanship of the cover. It fits like a glove. All buttons are despite Cover excellent to operate. It is much less dirt on the keys and the effect of the tapped key is prevented. Certainly the Sillikonhülle is not very cheap, but I would buy this again and again.
Update: After several months of use, I'm still happy. In daily use, however, has shown that the key is difficult to stow in your pocket. The surface of the silicone is slightly sticky, so that the insertion and retrieval of the key in tight pockets hard.
