Hey I just got a set today after a frigid ride to get a service done they work great however the cost for the grips plus installation time had I known what it would have entailed I would not have purchased them, my only concern was the fact for 30 miles I could not feel my thumbs this morning made me get them 200$ plus about an hour and a half to install about 280$ total I would have tried to find a better way to keep warm now that its all said and done I almost have to love them
