Nice! On the Rhino subject, do you have much experience with their hand grinder? I've got a trusty 8 year old Porlex but this is the first time I've used it for espresso. The fineness is fine (great sentence there...), but I reckon there might be some slippage between the nut that sets the grind and the bottom burr. There's definitely some wear on the little plastic nubs that give you the clicks.
Is the Rhino one likely to suffer the same fate?
I've seen that some people replace the nut with two nuts that lock against each other, but it seems like it'll be a faff as I'll be alternating between using it for espresso and filter.
