I have already posted in this thread but just wanted to pop in again as I just gave birth to our second child 4 days ago. WIthout the TENS I think I would have died, that's how useful it was for me. I cannot prraise this wonderful device enough. A second, completely natural, drug free labour for me thanks to the TENS.

ETA : I had no back labour at all, all contractions were felt in tummy, down low so definately don't need back labour for it to work.
