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.

I use for sciatica and back aches since 5 years and I recommand

great for back pain. I've recommanded to my family. Held during several hours per day, always effective for me. Better than drugs because no secondary effects.

Seemed new to me

I can't see how the model that was delivered (very promptly) had been "used". As far as could see, it was new! I was provided what seemed very honest & thoughtful advice & although it couldn't be guaranteed, the model I was recommended (TN-11) arrived very quickly. Thank you.

Great value

I received the most expensive machine at this price. Very pleased, good as new and very strong power. Well worth taking the 'risk'

Not a mark on it

You would not know this machine had been used. Not a mark on it and works well. Good power and decent electrodes.
