"I have used a maternity tens machine to bring both of my children into the world, and I can guarantee anyone that these DO work !!!
I thought at one stage that it wasn't doing anything, and so turned it off........ and then back on again, when I realised just how much good it was doing !
The ELLE TENS is wonderful to use, and kept the pain at bay right through to 8cm dilated, when a little pethedin was needed to help out aswell.
For all of us that wish to give birth as naturally as possible, these is an absolute must !"
