My daughter brought me this (shes 9) for my birthday (with my money haha) my feet are a size 5 and do fit in it. I wouldn't buy another one because its a lot of faf to get going (especially without clear instructions) but we will use it, and it's nice that it fits my size 5 feet in. I dont think you'd get away with it if feet were bigger than that though. Give your feet a treat with the One and Only Orbeez and the Soothing Spa! With a new wave design, you can now see and feel the cascading waterfall of Orbeez massaging your feet. The motor is loudish. They don't care but I was annoyed when I first turned it on...Umm, hello this is suppose to be relaxing! And the Orbeez are cold. The only way to have a warm experience is to put 2 cups of HOT water into it and get your maybe 4-5 minutes in before carefully draining the cold water and doing it again. SIGH. Yes they love it. UGH! And I mean they ALL love it. Ages: Boy 12, Boy 8, Girl 7, Girl 5, Boy 2. I literally am going to have to buy another one.

It's a bit of a pain draining the water out the tray before use but it does feel good even without the waterfall on. I think if I had just bought the little Orbeez balls and filled 5 separate tupperware containers for them all they would have been fine...But I bought this for the girls and now that they have all experience the LITTLE bit of motion with the Orbeez being spit out (a FEW at a time) they will no longer be pleased with a still bowl....
