Lots of fun ... not for my sub

This little gem packs quite a punch. I touched it to my hand on the lowest setting and found it quite annoying. Of course, the proper test was to try it on my sub. She screamed and cursed at me, especially when I did it twice more. I asked, On a scale of 1 to 10, how painful is that? She said it was a 7 at the lowest setting. The vibe makes it an interesting sensation. I press the button on the side and wait for a reaction.
