Been working with my primus and it truly is an awesome machine. Ive always used my sunskin handbuilt coil for shading and nothing has ever come close to the softness it can achieve. Unfortunately it works best with needla groupings 11 and under thus being limited in its usage.
Enter the Primus, jumps to life at 4v and does a geat job as a soft shader at around 5v. Pushes every needle grouping with ease and truly is the first machine I've been able to use as a soft shader with my 23 mags.
Dearly recommended to anyone wanting a soft reliable shader without buying a coil
