This not my first completely wireless pen style direct drive machine. But, it is the first that I liked. Well, maybe beginning to love. I have used Cheyenne Thunder machines exclusively for line work. But had been switching to another brand pen style machine to shade. That won't be the case anymore. The balance is great and the light weight characteristics of the unit are a big plus. I expected the battery to be much heavier, but I was Pleasantly surprised. The stroke is perfect for my hand style and speed. I have merely to hold it on course and the machine does the work. I have lined and shaded with it and found it equal to both tasks. It also punches color in quickly and with less skin trauma and redness. I like both levels of power constant and pulse. If I had one con to say is what that it was a bit fiddly to get used to switching from the two modes and then getting the power setting correct to where I like it. With having to hold down on the one button and tilt the machine up or down. Have been using it for about a week and a half now and I am getting much better at it. I absolutely love the fact that I can stand, sit, walk around and go in anywhere in my booth to get the right angle on the spot of the tattoo I am working on. The balance means that the machine is Not top heavy or ockward at all. I will buy a second unit down the road.
