The Labour TENS machine was recommended to me by a friend, and I thought it was fantastic too. I managed to get through a 33 hour labour with a posterior bub. I had a natural birth with no drugs -not even gas. I thought the Labour TENS was very easy to use, and very helpful for relieving my back pain. I gave birth to a 10 pound healthy boy after 33 hours of labour with no other pain relief. Great value for money.
