Any one used a Water Widget?

I got given a free water saving kit at Sainsburys that included a Water Widget that I'm supposed to screw between the shower head and pipe. It reckons it will save 70% of water. I'm pretty sceptical and expect it will slow my combi powered shower down, but it claims to not effect and may even improve performance!

Any one else tried one?

Well I like getting battered by my shower! I might give it a try to see what happens.
