| Yea its kind of like an eletric shock (lmao) but in a nice way !!!! ok i know that makes no sence !!! it basically send electrical impulses to stimulate your bodys natural pain killers (oo get me, i sound intelligent there lmao!!!)
When you have a contraction you press a button which gives you the electric type shock !
I found it really helped in the early stages as it took my mind of the contractions,so for a first labour it could encourage you to stay at home for longer, although when your in full blown labour its pretty much useless ! i turned it up the full whack and it did nothing as i was in soooo much pain ! so ended up ripping it off in temper !!! ha | 
Thanks Steph!
