$38.88 at Walmart. It works great I recommend you getting it. I have a lower back ache and I've been told try this and I did I've been using it for a week at same 9 volt battery that's what it takes still working fine. You can set the Hertz what will be the intensity. Then you can set the oscillation. Or how kind of fast it vibrates electrocutes whatever it don't like you but it's thin shocks I like that. I definitely helps my back just place the pads kind of not too close but enough on each side of your back or wherever and it goes right through and it works perfectly got two settings on it got two places to plug in at. And you'll see the pictures but yeah I recommend you getting this it does work good. When you go to Walmart they got three different places where they got tens things sitting at. I'm glad I kept looking cuz I had a cheaper one of the junk and found this one get this one you'll like it.
They work well
I’m still trying to figure out the settings . I need a video to show me exactly how to set it up .
I really like it because it helps me to reduce my pain - low back and tennis elbow.
Very reasonable price and perfect quality. Easy to register for warranty. 5*****
