I received my diablo swiss and have used it on a couple of tattooos so far. It is very well balanced and the adjustable give makes this machine an incredibly versatile tool. I look forward to using this machine in the future as one of my mainstays. I like it so much, I may buy a couple more just to make sure I have one to back up the one I have. The more I use it, the more I like it, and it is well worth every nickel of the $400 price tag.
