Ambition MARS-U Wireless Tattoo Machine with Adjustable Stroke - Rotary Cartridge Tattoo Machine Pen with 1800mAh Power Coreless Motor Digital LED Display for Professional Tattoo Artist Black

This machine is great, for lining and packing color, and black and grey shading as well! Well worth the price!

The negative review about the batteries, was using the wrong cord. Yes it's USB-C, HOWEVER, it will not charge on long cables, only short ones like the one it came with. I don't know why, but it's like that with my Ambition Soldier too.This machine is so quiet it's almost hard to know it's on! Almost NO vibration. It's super great value, better than any Mast I've tried.

This is by far my favorite machine I have used, and I have used quite a few. My favorite feature is definitely the adjustable stroke. This allows you to do pieces with only one machine, which saves supplies when having to set up second machine for shading. I’ve used it for blacking out, Fine Line, and pepper stipple shading so far and I have only good things to say.

Me encantó el producto y todo viene muy bien y completo

I was super excited to try this machine I turned it on started & it was quiet & smooth. About an hour into my tattoo it got loud all of a sudden, a little clanky. I seen a YouTuber review it & he said they fixed this issue but obviously not. Also I’m using big wasp 9rl needles and the needle cartridge was kinda coming out a little bit so I kept having to push it back in for my needle to come out of the cartridge. Kinda disappointed I should’ve gone with the mast fold 2 or 3 tbh :/

This machine works great. I’ve used it on multiple tattoos. I been tattooing 10+ yrs. The inner changeable throws works well. Adjusting your need works well. I use Kwadron needles. They need a little extra help ti get them locked in place but its not a big deal. This machine is ridiculously quiet and the battery is insanely good. Ive used it on 6 hr sessions and it barely drained and keeps its strength so far. I have been using it for about 1 month. Its a little heavy compared to the bishop. It throws 3 tight liners ti 15 mag shaders. Solid!So far so good.

Been using this for my black and gray work. I like the adjustable stroke.Mainly run it at a 3.0

I bought this machine because I could tell my ambition soldier was going out the door after a year of use. I wanted to try this one because of it’s adjustable stroke, but it’s lack luster. The first one I was sent was defective, I returned it for a replacement, but I still have to turn the voltage up much higher on this machine than I usually do to pull a line, and the battery life isn’t as good as the soldier. I ordered another soldier, I’m hoping that one will be as good as the last one, planning on keeping the mars u as a backup machine. Pros: quiet as hell, sleek, light
