I bought a brand new labour TENS machine from Lloyds Pharmacy, and it broke just after being put on, rendering it useless and leaving me with no pain relief until I arrived at hospital fully dilated! I'd recommend that you don't buy one from them, and go for the ones that Feebs has recommended to you

Mine broke too!!! I was about 7-8cm by that stage mind and about to go in the birthing pool but I was so cross. Have you taken yours back??
On if they work - I *think* mine did - was a definite distraction anyway and if I have another baby I will def use a TENS machine again - not a lloyds one mind!!!
:\)
I haven't even thought about taking it back yet! I intend to contact them soon though, as my son is 4months old now, so better get on with it! Lucky that yours lasted that long! lol
