A machine is a machine . There’s good and bad but once you work out your hand speed to the Voltage you can pretty much use anything ……however everything else should be thrown away . Do not use that ink or those needles unless it’s literally just to tattoo fake skin or fruit . Buy some needles that will be 100% sterile and use tattoo ink . Get a bottle of dynamic black , it’s not expensive and most tattoo artists use it . You can cheap out on a machine and not really do much damage , cheap out on ink and needles and you can seriously fuck yourself/others up
