I signed up for this forum looking for a rotary to outline with, and read alot of reviews on alot of machines. My attention was drawn to the overwhelming "buzz" about these machines. Even checked the years of tattooing from alot of the people posting knowing they were probably lining as fast as I do. Took the dive and took advantage or the labor day special and purchased a 3.6. Out of the box no adjusting or anything outlined two smaller tattoos effortlessly, then busted out a 1/4 sleeve lining project on my piercer with it later that day. Played around with the give during that time and i think i like it better straight outta the box balls to the walls. A few days later I did some smaller delicate lettering with swirls with a 5l and a 3. Ran a few strokes and switched back to a coil,felt like I was going to filet the lines open. I think it was a weight issue for me. Did a piece this morning with lettering small again and put a new skateboard bearing over the adjuster and nailed it. I think this is definetly an all around machine to do everything with minimal adjustments. I think the support from Gaston on this sight is phenominal and the opinions are legit, raw, and unadulterated. I purchased the 4.0, 3.2 rollers and havent really felt the need to even change them out. I would recommend this machine to anyone using a rotary that doesnt have one or to any one that hasnt used a rotary and looking to make an investment into rotaries. Excellent product, and feedback. Thanks
