We were given a "pee cosy", basically the same thing. It didn't work - as Pink Lily says, just fell off and was too small for Wilf's winkie (his dad was very proud!) 
The best wee fountain was the time Wilf peed all over the cat while being carried naked to the bathroom for a bath. The look of sheer horror on the cat's face was hilarious!
Thankfully now at 9 months we don't get them quite as often...
