It's madness, a simple plug/play component !!! Reseller's are absolutley CLUELESS !!!That's exactly how I feel, but we're lucky enough to be able to sort out stuff for ourselves. If you can do that sort of thing, it's very frustrating to have to put your problems into the hands of a system that doesn't want to cooperate with you.
I presumed i was purchasing quality, it is well made but aftersales are NON existant...I'll post pics of control ring pcb and it's 6 connections...I KNOW the ON/OFF pins on the PCB and the speed selection pins...PLUS you can see the 5v (i presume) for led's main power.
