Feels good but is loud and the tentacles are a bit too long if you have a small head.

I had a concussion in an ATV accident and thought this might help tap out the stabbing pains in my head. But the arms didn't fit my small head in the right spots. I believe it might have worked if the arms had been bendable and would vibrate the entire length of each arm. Unfortunately, it just didn't work for me.

I try it and I don'tLike it at all.
