I don't use the rubber ones but "flossers" which uses a piece of actual floss. I've found GUM brand to be the sturdiest, some brands fray easily which I hated. These made me go from literally flossing a few times in my life to doing it multiple times a week. Once you get used to the clean feeling you'll feel just like you hadn't brushed your teeth if you don't do it.

It went from this very unpleasant finger tourniquets and hands inside my mouth to doing it one handed while I read or watch a clip online.
