Does what it says and more
I bought this to replace my TENS unit that ran on 9V batteries, which worked fine but I would always need to change the batteries often. I’m so glad that I got this rechargeable one! The battery life is superb, and I haven’t had to recharge it yet (bought this in January) and it’s way more powerful than my last unit. I love the different types of modes that you can use. The massage mode does feel like a massage - I honestly thought they were exaggerating when they named it that until I tried it. Can’t go wrong with this for pain relief.
