Very good purchase

3rd Nov 2014

I am using it to relieve pain in the lower spinal region. It is effective. Easy to use. A good size to keep in my pocket. I would advise others to try using one. I would like the sheets the pads are kept on to be made of stiffer material.

Natures Gate Tens

Maria on 26th Jun 2014

I bought a tens machineTN20 from natures gate in hope that wil help me regaining muscle strength and elasticity after a three month period inactivity. I had an ankle surgery and after three month of physical inactivity my muscles lost their strength an elasticity. the machine is very easy tu use but it doesn't work for me as I expected. today i got a call from Naturals Gate uk in order to help me with the machine. I explained the lady I was talking with what my problems is and I understood that what i need is a stim machine which stimulates the muscles fibers and ligaments by extending and contracted the muscles. If you have the same or similar problem as I have, a stim machine would be more efficient choice. my advice is before buying, feel free to contact Natures Gate and have a chat, they are very kind and helpful. My english is not so good and it took some time for me to find the proper words when talking on the phone, but the lady was very patient with me.

High power at a low price

The PowerTens si the third unit I have used and is by far the best. It is easy to operate and is more powerful than those previously used and I have found it very effective in relieving my sciatica and associated knee pain. Highly recommended.

Natures Gate Tens - Model TN20

I.Mills on 21st May 2014

I own a few Tens machines & think they are a great invention. I have Chronic Psoriatic Arthritis together with fybromialgia, and although I have other battery powered tens, I needed something that was more portable, compact, reliable, easy to use not fiddly or complicated, but to have the capability of dealing with complex pain & to be powerful. The TN20 I have to say does all this, i was extremely impressed, so impressed I use it more than my others. Its equally as powerful as my other tens if not more so, I find the "Modul II function" very helpful with my condition. It looks great, its a very discreet machine & if I were to recommend a tens for everyday use & provide a good choice of functionality for pain control for the right price, this is the machine & this is the company to buy it from! Natures Gate tens have been very helpful indeed, always there if you have any problems & ready to help at anytime, providing prompt help, even out of office hours! not like most other companies. I cant fault them, Great product, Great price, Great company. What more could you want

Good high power with this machine

Harrison James on 14th Feb 2014

I have been using tens for many many years. Having had this one a month and using it twice a day I can say it is simple to use and the most high powered machine for its price I have ever found. Would recommend.

I use this machine for repetitive severe shoulder pain. I feel there is a marked improvement and am pleased with my purchase.
