[This review was collected as part of a promotion.] Having tried a smaller version of a TENS machine some years ago I looked forward to trying this one. For me it is really good and helps with the pains in my knees. With my previous machine you had to buy a special gel to use on the electrodes but with this TENS you only use water. It has an adjustable velcro strap and a timer that you can set to your own levels. Although the instructions advise that the power intensity increases after 10 minutes of the 30 minute cycle it is still a shock when the power boosts but the relief given is worth it in my opinion. As there is no additional expense after the initial purchase I would recommend anyone who has knee pain to try this machine.

[This review was collected as part of a promotion.] After suffering from football injuries to my knees from a young age, I've been having problems since my 30's with them. This has taken out the pain to a degree and it's helping me get back to light running which I've not been able to do for sometime now.

[This review was collected as part of a promotion.] My own physiotherapist in a box! I’ve had knee pain for years and wish I’d discovered this sooner. Very easy to setup and start using. You must remember to slightly dampen your knee and the built in pads, two little metal clips connect the control pad to the knee, once connected you select the program you want and the strength of the program, it has an inbuilt timer which counts down the program and automatically turns it off once the program is finished. You can increase or decrease the intensity of the the tens machine, I would recommend starting with a Low setting until you get used to the sensation. I found that I needed to use it regularly to gain the full effects but it has helped with the pain levels.
