If you're 'wondering,' it WORKS, and works great, no joke. At the price- for me- it was WORTH the TRY.
I would suggest buying extra sticky pads at the same time. Especially if you have long hair and use it anywhere near your neck, lol. It takes some trial and error placing the pads just right, but when you get em there- you WILL notice the difference at the end of your treatment, as you move on thru your day.
The treatments available range from unnoticeable to electro-shock type therapy, so be careful starting out as you learn all the things that it can do.
It's also fun to chase your spouse around with, like the dog's shock collar! It's very versatile!
Seriously- if you're even THINKING that you may could use one of these- DO YOURSELF A FAVOR & GET IT. It actually works!
