Works
Works but somehow the life isn’t as long. Reminds me of old days when the battery drained after 12-24 hours even not using and had to keep it charging.

Saved me money and my Tens unit from the garbage dump
What a find on Amazon. I have an older tens unit maybe 8 years old and used a million plus times. Every household in America needs a Tens Units for aches and pains. Anyway the battery got weak and they do not make this unit anymore which I like and is easy to use. So I ordered this one and its safe to use but a little more powerful. It makes my tens unit give that tingling feeling all over again.
