From a long time ago I was dreaming for something like this

It was given to me as present and once I tried it I ordered 3 more (I'll put on every of our cars 2 of them - one for driver and one for passenger). I also recommended this to all my friends and I'm sure at least half of them will order this too.
There is only one recommendation to NanoGrip - if it is possible to produce this things in different sizes (for example I'll need one narrower).
