I have never written a review before, but do not people to buy this for their kids and their children be as disapointed as mine were by this product... Where to start.. Firstly.. it is made of a cheap plastic that feels like it is going to break the second you touch it. The orbeez balls can be warmed in warm water, but quickly chill back to cold with no heating element, and they also break down to a mush after the first use, out of the two bags supplied we probably have 1/2 of a bag still whole balls, the rest are a mush in the bottom of the (Not very) soothing foot spa. the are cold wet and slimy within about 5 minutes of switching the VERY NOISY machine on. My daughter was really looking forwards to using this, but is so disapointed. Its nothing like the hype of the adverts... a cascading waterfall it is not, soothing it is not... waste of money it definately is!
