We love our flow ring. They are so much fun! We actually purchased a second one. Not only are they good for the mind, but they are also very soothing. We bought the second one for our calm box. My daughter loves the feel of it and even tries it on her feet and legs, which is silly and can tickle, but makes for more fun. It was a great bonus that it offers a way for children to calm themselves down whether they are just over excited, upset or just need some down time. I highly recommend it!
