Have purchased 2

I have used TENS technology for many many years. I was in a car accident leaving me with severe lower back pain. I do not like taking lots of pills as i tend to get side effects so started to try TENS. Having paid for much more expensive machines in the past I have found this machine to be excellent. I keep one at home and one at work incase I think I do not need it and the pain worsens during the day. The pain control with it on is better than pills. It does not get rid but makes it much more managable. My only quibble is that I would prefer to have buttons for the power level not the knobs but that is just personal preference and has no bearing on the quality of the machine.

Power TENS - TN20

I am very pleased with this machine. It has a remarkable ability to stop my cartlidge pain in the hip. Seems to work in approximately 10 - 15 minutes. I always set the timer because it tends to send me to sleep. I am much happier using this device than take loads of pain killing medicine which was my other option."

... only thing I get some comfort from I will recommend it to other suffers

I`VE had a broken COCCYX for over 3 years in constant pain this TENS is the only thing I get some comfort from I will recommend it to other suffers .

Best Yet

This is the third TENS machine, which I have bought for my husband and it is by far the best one. He uses it mainly to relieve the pain in his back muscles either side of his spine. Unlike one of his previous TENS machines, this one is economical in its battery use and has a lot more programmes to choose from, which he is still experimenting with. My husband would recommend this TENS machine to anyone who suffers from muscle pain.

Very good purchase

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

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.
