Got to do a little playing around with the machine last night. There is a little bit of a learning curve to it but once your adjust it to your liking it runs extremely smooth and quite. Did some color blending and it performed just a smoothly as my Gen 8 except it literally feels like you're holding a pencil. I'm digging the power supply, it's about the size of a pack of cigarettes and it feeds the machine smoothly and consitently. I found my sweet spot on it and didn't have to touch it the rest of the tattoo. No noticeable vibration at the speed I was running it at for color blending (didn't get to line with it yet) but the only time I feel vibration from the machine is it's turned way up and adjusted to where it's hitting it's hardest. Didn't get a whole lot of time on it yet but so far so good. Being able to adjust stroke and hit on they fly during a tattoo is pretty freaking awesome. So far I'm really impressed with it. Will report more as I get to do some lining and black and gray pieces with it.
