For 20+ years this grinder provided a consistent grind that's good to the last bean. Very handy for one cup and it gives you something to do while the water comes to a boil.
Positive Product Points
Consistent grind with an infinite range. Every bean I put in the hopper gets ground with very little static or mess.
Negative Product Points
There is no way to lock the adjustment wheel in place. I have trained myself to hold it with one finger while I grind but a lock nut would be nice.
I have been using this grinder for 20+ years with only the best results. It provides a nice, consistent grind so long as the adjustment wheel does not turn during the grind. I have trained myself to hold the grinder with my left hand with my forefinger on the adjustment wheel. Also, there are no markings on the adjustment wheel. That makes it's difficult to tell if it's positioned correctly or if it's moved. Long ago I put a drop of white correction fluid on the adjustment wheel to give me a point of reference and it's still there.
I tend to use this grinder when I am making one cup of coffee (16 oz). I measure the beans then grind them all up. There are no places for stray beans to hide and it's easy to make sure you get all the ground coffee out. This is very nice when sampling different coffees.
It's not too much work to grind up for one cup of drip coffee. It's quite a chore if you want espresso grind or if you want to make a full pot.
I got this before there was an internet. It was quite a chore to find a good manual mill, but eventually I found one in a small coffee shop. Blessed be the small coffee shops that stray from the corporate norm.
