I just bought an Obi TENS on Ebay for £20!!!! My friend gave me her spare electrodes as she had borrowed a TENs for her labour and got extras. Looking forward to trying it out!!
Yup it arrived the other day, in perfect condition, well chuffed!! Gave it a wee clean over with alcohol wipes anyway and it was ready to go. Only thing is having to get OH to put the electrodes on, wish there was an easier way!
