Have chronic back pain for over 10 years now. 1st time user of tens 7000. Unit is great.
My lumbar muscles have been giving me trouble causing pain in my hamstrings and calves. Using this for 30 minutes a night has relieved most of the discomfort. Very satisfied!
This is my 2nd TENS unit. The 1st one is 25 years old so while similar this unit is definitely an upgrade. Portable and easy to use.
