Oh you know I have to ask. How?
The one I have here gave me a little grief, but it was neglected for a while (I assume it takes at least a few days of non-use for the motor pulley to seize solid.) and it had loose wiring in the female connector, and the pedal, and at the back of the male connector. I could blame it for my "sparkling" issue too, but that was 100% me.
ETA: I guess I'm asking, do the parts seem better, or it runs smoother, or,...?
I think for some reason that the German 400 series seem to run quieter and a little nicer than the American and Canadian ones.
