Never had any problems with my older Novak kit, or my recent Novak GTB kit, they have been utterly reliable. (Did get a bonded rotor in my 6.5 motor, but according to the box, this is actually correct
). The only piece of 'blue' kit i ever bought was a charger, and it packed up after 3 meetings for no reason. Did have a dead old nosram (when it was dan marson's dad's stuff (which was great!). Tell you what, havent touched them since.
