Seriously, I haven't had issues with any garmin or cateye bands.
Just the OP apparently is having issues. I still have my garmin quarter turn mount for my edge 500 using the same two o-rings I put on it 10 years ago. And Garmin gave me a a lot of extras too that I still am waiting to use. Most sensors and crank magnets I have nylon wire ties holding them on.
