Bought this item for my 11yr old daughter that does not like to floss, even with the child style floss sticks. Absolutely love it! She now has no problem with flossing! Was definitely worth the try. The handheld part of it seemed a little bulky to hold to me, but does not seem to bother her nor is it difficult for her to hold afterall. So very pleased with this product.
I had been advised by my dentist to use a water pic for some time si I finally got one. I have seen for myself how much it helps my gums and overall oral hygiene. The only drawn back to the 360 is that you have to buy its pics only. It isn't compatible with other brands.
