Dear Sir/Madam,
The device sent to me initially was defective which was annoying! However, having contacted you I was sent a postage returns slip to avoid any loss of money on my part. A replacement unit was sent and it has been found to work very well indeed. Within 3 days of use there was already a marked reduction in the pain I was suffering. Continued use has undoubtedly reduced my pain by a considerable amount. I have additional spinal problems which, it seems, will continue to aggravate my sciatic nerve. The bonus is I now have a medication free device which will eradicate most of the pain until the nerve settles down again. I have worn the device around my leg and around my waist although I found the waist strap too ‘delicate’ for the job. In either position, the pain relief is impressive.
