[au naturale]

I have one, it's a bit weird and can be quite uncomforable if you don't have enough of the gel on. If you've ever been to the physiotherapist, it's like the little zappy things they stick on you to deal with problem nerves and muscle.

I've only had mine a little while, and the day after I used it, my boobs did feel like they'd had a workout and I was quite aware of them all day, whether that will result in much growth though I'm yet to see.

It was cheap though, so I'm giving it a go!
