This grinder lasted 6 years. It's vinyl/plastic parts brake too easily. I gave up on fixing them. Will buy a different grinder.
Positive Product Points
good price/value very good fine grinding Baratza's website has very good instructions on how to fix problems replacement parts are cheap.
Negative Product Points
Noisy demands some care and maintenance replacement parts take too long to arrive some vinyl made parts (upper burr flange) not robust enough.
I have this grinder for 4 years. In all this time I had to open / disassemble it twice.
The first time was to regulate the grinding, too coarse for espresso. The second time was to replace the flange that attaches the upper burr. Baratza's website has some detailed information on how to do these; it is not complicated but you do need to have basic familiarity with screwdrivers and simple machine disassembling/ reassembling.
Also I'd recommend removing the top container and upper burr every 6 months and doing some basic cleaning.
The knob on the right would fall to easily, in the beginning. By recommendation of Baratza's site I fixed it with a little of tape.
In all this disassembling and cleaning I became surprised on how little tear the burrs suffered. This looks like a machine that will still last a lot of time.
This machine is noisy. A little less than cheaper coffee grinders, but not a good thing to turn on when everyone else in the house is sleeping.
In dry days, the plastic container that receives the ground coffee tends to accumulate static electricity that makes it annoying to handle finely ground espresso coffee. But I live in central Alberta, in the Canadian prairies, a particularly dry place during winter. People from warmer & more humid places may not have the same problem.
It took me some time to get the grind good enough to do an espresso in my Rancilio Silvia. Expect some experimentation on this.
I don't remember the name of the online retailer I bought the grinder from. Sorry, it was 4 years ago.
Three Month Followup
I had to open the machine again, to regulate grinding.
One Year Followup
In my comments, 2 years ago, I wrote that the vinyl components are not very robust. That's what made me give up on this grinder. It broke again and I don't have time & patience to fix it for the nth time. Will send it to the recycle station and buy a different grinder.
