3 Pc Rubber rings

Got the three-pack and honestly the different sizes came in handy since I wasn't sure which fit I needed. The rubber has a bit of stretch but holds snug once it's on, and clean-up afterward is quick.

The three different sizes meant I could actually find one that stays snug without pinching, which was my main worry. Only gripe is they take a bit of fiddling to get on smoothly, but once they're in place they do the job.

The snug fit is secure and I didn't have to readjust, but the rubber has a strong smell straight out of the package that took a few washes to fade. Fine for occasional use, though I wish the material felt a bit softer.
