We demonstrate our devices to hospitals, physiotherapists and other medical practice. The units that we use for the demonstrations are new, however as they have been taken out of the building and used we do not feel they should be sold as new afterwards. If you purchase this item, you are purchasing one of our Digital TENS Machines that was used for demonstration purposes and has been checked to be as new condition and approved for sale. It comes as a full set and has the same 2 year warranty as a new machine.

This machine could be one of many machines we offer and is at least 50% discounted as an ex demo.

Hospital Ex demo digital tens machine

anne on 15th Dec 2021

this was bought for my husband who has had several operations on his back but still suffers with pain, although this will not cure his pain, it has made a positive difference by reducing the pain level so he can sleep and carry out short walks, I would certainly recommend one of these machines for back pain.

The machine arrived in perfect condition. My wrist was extremely painful after rose pruning (Ihave Rheumatoid and Osteo Arthritis), I attached the pads as indicated and kept the pulse going for two hours. Amazingly the pain disappeared. I thought it would return overnight but the joint has remained pain free. It is just a little too delicate to resume pruning. I recommend the Tens machine for sharp arthritic pain in joints

excellent service and product

I have bought tens machines in the past more expensive than this one and although it is EX-DEMO it came well packed and it looked new (no marks or scratches). It is a well made machine you can see it is quality just by the feel of it and the user manual is excellent it tells you all you need to know about how to use it in great detail. Would highly recommend this company and the tens machine they do prompt dispatch as well

Brilliant Rolls Royce of tens machine no signs of previous use. Used it on and off for over a year now, it's a brilliant steal at this price and a gd price if you have to pay full price for one. I depend on tens machines sometimes have used loads of different ones from Nature's Gate and this is definitely the best one.

Good buy

Gift for my father who suffers with Arthritis in his shoulders and back. He said he has managed to reduce by half his painkillers by wearing this all day. he has had it many months and uses it every day. He is only on his second set of batteries. He buys the back pack and blue squre multipack of sticky electrodes to go with it and they seem to last well enough.

5 stars for price, speed of delivery and the machine

Louise on 9th Jul 2018

I am very happy with this. I found the machine I was sent for much more money on Amazon and this looks like new. Also works very well for reducing the pain in my shoulder by half.
