Save your money buy one with bettter adjustment knobs........
You get what you pay for the tightening knobs are all plastic not even very strong plastic first time I adjusted the height and tried to use it, it fell back to starting position.(Almost messed up a nice tattoo) After I readjusted it and tried tightening it a little more the knob broke reveling a cheap Philips screw melted on the inside to hold it to the knob. Only reason I'm not returning the product is I'm a little creative and made it work. I will add pictures if ppl wanna see what I'm talking about.
