We have been hand grinding our coffee beans using a small Turkish mill for over a decade. It's time consuming, but it has been worth it considering the quality of espresso we get. Recently I came across this little gem. It's USB rechargeable and uses modern ceramic grinding gears. We only use the milling function, but it works really well and is much faster than our hand mill. Don't know about longterm use, but it appears to be well made. Very happy with it.Here us our mobile set up, with a stove top espresso pot, on our Origo1500 alcohol stove, inside our former FedEx DIY Stepvan travel home conversion.
I am enjoying this grinder. Once I found my preferred coffee coarseness (which took a few brews) I have settled in to a daily morning routine.
