I am truly amazed!! I kept seeing adds on Facebook, and had a tattoo coming up, so I figured why not try it! I didn't have any expectations but wow! I sat a little over 4 hours for this and I hardly felt ANYTHING. The end of hour 4 I could hardly even feel anything right on my shin even. Really impressed. I will never not use this, and I wish I knew about it for all my other tattoos as well. Made getting tattoos a whole new experience for me. Already scheduled another.
