ive had my nedz rotary. about a couple of weeks what can, i say about it not tried it for linning yet used it for shading black and grey with white spring its good not choppy at all . like the rca ,could do with both ,clip cord and rca but i bet if we all ask ed nice it might b on a future update .now more on the machine.ive coloured with it using red spring and screw turned right down , running at 4 volts ,i have to say puts colour in faster than any rotary ive used.and i own quite a few my only real gripe is could do with a bit more hand clearance,runs smooth as .silk i spoke to ed by email about my machine he was super nice, responded quick to my emails ,and any issues ,i had got dealt with quick love the machine 3.5mm stroke in purple .will defo buy another ,give em a try .u whont be dissapointed i aint thanx ed all the best p.s will post photos soon as iget some healed pics
