I'll be honest with you... I was a little worried about using this neck shocker... I mean neck massager. :-)
I have had many traditional electric pulse treatments on my lower back over the years, but until now, had never tried it on my neck. Once I was finally brave enough to turn the thing on, I realized that it wouldn't start out too intense. It allows you to gradually increase the intensity for your comfort level.
I am a big guy, but it seems to fit around my neck okay. It does what it says, but I'm honestly not sure how after I will use it. I don't think it will be a daily massage device for me, but rather something I use when having specific neck issues and need extra relief.
