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.

TePe easypick, the orange ones. Feels a bit unusual at first but basically you just push them inbetween the teeth once and pull out again, and all the dirt comes out with them.

My dentist recommended those, works like a charm for me. Although keep in mind they're thicker than dental floss, meaning they may not fit between certain pairs of teeth if they're very close together.

I use Oral-B's floss picks (mint flavor). Way more easy to use than a thread. I also use an inter-dental brush.
