The first time Theresa used the ring, she was a little unsure how to insert it. But now she's a pro, with a twist method to get it in and a fishhook move to get it out. No sweat.
She also uses the stickers that come with each ring to remind her when one went in (twist...) and when it needs to come out (hook...). We've got electronic reminders to help you with that, too.
It's like a little invisible secret protection plan that I'm on.
