Keep them warm.
Decent product, kept my hands warm as as described. I will say the grip does like to spin and you do have to repeatedly adjust it. It is easy to get on and off so it’s not a permanent farkel.

I installed this on an e46 325ix sedan, they only worked, one of them is just a little loose. I don't know how long they last, because every time I open the bonnet, the lever bothers me a little?

Driver side is smaller and every time I open the hood it fall down. I have to bend the lever to open the hood to install it. It look good but I’m not happy with it and I’m scared ti drop it while I’m driving. I have to check on it every where I go to be sure didn’t fall
