I've got one of these.
It's been very useful when fishing with my three year old son, as kids that age have a bit of trouble handling anything longer. PLUS it really bends, like Jeff says... so even a very small perch will make itself felt. It also means that I can get everything we need for a session in a very small backpack, which means we can easily travel to whatever venue has been selected on a pushbike with him on a seat on the back, which is a right laugh in itself.
Worth getting too if you just wanted to have something in the boot of the car for those moments when you're out and about somewhere, cross a piece of water and think "i wish i had a rod with me!"
