URGENT - TENS Machine query

Hi folks I bought the Mama TENS machine online. We tried it out last night and put on the sensors as directed. But I couldnt feel anything even when I increased it to the highest level on programme A. I also tried the other programmes but still couldnt feel anything. I'm about to contact the company I bought it from, but just wanted to check what exactly it should feel like and at what setting should I be able to feel the sensation. I'm due in 2 weeks and the baby's head is engaged so I'm afraid I wont get a replacement in time Thanks

it should feel like pins and needles and u should feel it even on the lowest setting.

i rented one from mothercare but havent tested it yet... Did you tried to use it with new batteries maybe???

thanks - its definitely not working so. Tried everything. Waiting on company to get back to me
