Rhein Wireless Tattoo Machine EM145

exelente equipo muy funcional cumple con las espectativas.

Westley Langdale
Poor performance

The power is very soft even at max level, also the cartridges are difficult to remove once they a inserted into the machine. I do like the weight and quietness though.

William Snavely
incapable of maintaining set depth

I used my machine for the first time tonight for line work, it was gripwrapped, and i held it to avoid the depth scroll wheel, but kept losing depth. the smooth/sensitive wheel action I think is too easy to slowly turn inadvertently, or it’s vibrating to resting depth on its own... otherwise the machine is fine. is there a way to adjust tension in the adjuster?

How to clean what rigth? disinfection and sterilization

How to clean what rigth? disinfection and sterilization

I bouth this tattoo machine and get it view days ago. Good power, strong line and cool painting.
I have no idea how to desinfection this machine.
Motor and grip - integrally.
Please, create instruction - how to clean, to wash and disinfection and sterilization this is machine.
Thank you

After this, i ill do 5 stars. But now, only 3, because sterilization is very important

1.Wipe the needle port and the handle with disinfectant alcohol
2.The conventional disinfection method can be ultrasonic cleaning (alcohol as the medium) + ozone disinfection

Fabian Harrison

Really good battery life, well balanced and very quiet
