Easy and works well
Device is awesome, reliable and effective.
So far the tens unit seems to be working. I only have it for a week, but pain has improved..
Worthed and good item with doubt. Excellent
Read about it on Amazon read the reviews of which almost 100,000, overall great machine used it the first night I received it for an hour that night was first night I slept more than a couple hours in years, next morning was first time I didn’t have severe pain and it’s been very management since I use the tens7000 morning and night for 1-2hrs each time.. was the best $50 if spent in years. So if you want a good tens unit you can’t go wrong with the tens7000.
