Three rings rather than one, so you can work out which diameter suits instead of guessing at the counter. Each has two raised tabs to grip, which makes getting them on and off considerably easier than a plain band manages. Silicone throughout. Straightforward equipment with nothing electrical about it.

Warm water with a little neutral soap, then a thorough dry, is the whole of it.
