They work

Inexpensive, sit vertically on the bottom, good size for small hands.

These rings sink pretty fast and stand up so they are easy to pick up.  They also feel durable and have bright colors!  My kids are enjoying playing with them!

I have taught swimming for 15 years and use these in my classes. They are the best dive rings I have found recently. They aren't the cheap light plastic, but they still don't seem to have quite the quality and duribility of the diving rings of my youth. But the best so far. Besides that, the only issue I have, is that they will fall over and lay flat on the pool floor sometimes making it difficult for students to grab. It is a little discouraging for new learners. I would still recommend them over most of what I see these days.

20 month old loves these.  She can put them on mommies wrist once she has retrieved them.  Wonderful product.  Sinks to the bottom but stands upright.  Perfect to dive down and swoop up without having to struggle at the bottom trying to pick up.  Used dive rings from walmart at swimming class, but these seem to stand up better.

We bought these because of the colors.  Different from what you get in ther store.  The pastels are a nice change.
