I can’t comment on those models,but I have the Baratza Sette 270w. It’s over 5 years old now and the gearbox shaft itself a few months after warranty ran out… I contacted them and they told me it was a known issue in the older models that they had since fixed and then replaced the gearbox for free out of warranty. Ideally it wouldn’t have broken in the first place, but props to a company for fixing the problem when they had no legal obligation to.
