I would recommend this grinder, I have used them alot in trade use and they very rarely fail. Besides the switch and heat issue there biggest con is probably there price but there build quality is one of the best.
A quality built grinder that isn't to big but more than powerful enough for trade use, the clutch adds a bit of safety for the user,
They tend to get hotter than other grinders which doesn't seem to affect the performance but they eventually get to hot to hold, the top mounted switch can be hard to reach in some positions,
