It was so nice to grab onto the grips but unfortunately they didn't stay in place and I got tired of fitting them back onto the rim. Also, they were thicker than I had anticipated so they rubbed through narrow doors. I'll try using tape I guess, but the thing is for as much as I paid, I shouldn't have to do that.
