FM function, soft and hard adjustment, stroke adjustment, slow prick mode, prick mode, voice function, buzzer, gravity induction, magnetic induction, ...... more and more functions are added to a small tattoo machine inside.

I have always wondered if there will be many tattoo artists who do not need so many complicated adjustment methods and functions. They can only operate in a simple pressure regulation mode. After inserting the needle, they can start to tie directly.

The more functions, the better, or is it better to pick them up?
