My husband and I really enjoyed this toy! We love experimenting with one another and this was perfect for fulfilling his needs while Mother Nature visits once a month;)
Not hard to use or clean at all! I may have enjoyed it a little more than he did actually; we will definitely be trying the others. Only complaint I would have is that the unit that holds the folds together comes off track very easily. You have to align the tracks right on one another in order to get it to properly close and hold together. Not a deal breaker but would be nice to see future products improved accordingly.
