This review is for a refurbished machine.
I bought this grinder for my morning coffee, which is normally drip or french press, but I also experimented with it as an espresso grinder after performing the calibration for finer grind. The stepped adjustment ranges from 0-40, and covers everything from fine moka pot grind to coarse french press. In my experience, the grinder performs outstanding for drip, french press, vac pot, and moka pot brewing methods, but does not have the uniformity required for producing great shots of espresso. The timer runs for about a minute when set to its full length (enough for a pot of drip) , but as mentioned, the timer knob is prone to fall off during operation. A bit of tape on the knob helps remedy this. There is some static when opening the bin, and chaff also tends to collect in the chute from static. The static issue is fairly minor, and doesn't create much of a mess.
Even though the grind quality falls short for espresso , this grinder will shine for all other home uses. The construction is very solid and heavy, and taking it apart for cleaning or maintenance is very simple. The grounds drop straight down into the collection bin, so there are no grounds to sweep out between uses. I have used mine daily for two years with no problems whatsoever, and would highly recommend this machine.
