The main problem is that I mostly use 8mm fitting for PFTE tube, which doesn't fit to this extruder. The second one is that it's pretty hard to tighten the idler perfectly - either the motor slips or it just doesn't push the filament.
The only benefit I saw so far - it requires much less plastic than other extruders to print :)
