Review on Premium Anti-Slip Silicone Brake Handle Sleeve - Ultimate Protection for Road Bikes and MTBs, 2 Pairs (Black) by Derrick Patterson

I'm giving these a 4 star rating because they appear to be of good quality and will no doubt be durable once fitted. My problem is with the installation; I haven't been able to install any of these on Tektro brake levers in my entire life. After about 30 minutes of soapy water, I was only able to advance one of them 40% before it wouldn't move in any direction. I ended up having to cut it off, wasted. Good thing the bag I got came with 4 handles. I might try again if I have a full day to work on installing these things.
