We really love these, I've bought 2 sets of pipes and 1 set of tubes and they are such good fun (even for an adult!!) and have decided to upgrade them from the bath for water play in the garden. They're bright, durable and work nicely - if the suckers are good...out of the 3 sets i've bought one pipe wouldn't stick which i'm yet to remedy but i'll probably exchange the sucker on it as they are fairly cheap to do, if I can't get in contact with the company. Its fun to use them with the tubes, as some can join up, and also the caps can be switched on some of them too. More is definitely more with these but the set of five is a good place to start. They're loved by all my small people age 1-10
