I used a TENS machine very succesfully during my last labour, but it wasn't a great one - just a standard one from Blooming Marvellous I think. Anyhow, the leads all came apart half way through and it didn't have a booster thingy. I was just wondering if it would be worth getting a proper obstetric one with the booster button? Or is this just a gimmick? Would any old bog standard TENS machine do? I'm thinking about the neurotrac one, if anyone has experience, or any other recommendations. Thanks
