If you are willing to do a 1-minute cleanup every day, this grinder is a bargain that will produce good espresso.
Positive Product Points
Will grind fine enough to choke my Gaggia Carezza, without modification of any kind. Good quality burrs. Marked settings produce fairly consistent results. Slow speed a big plus - no damage to beans and little static. Easy to clean, but see below.
Negative Product Points
Good thing it's easy to clean, because you should do it after each use. Timer is a silly add-on. An on/off button would work better. If you let grinds build up, grind gets coarser and you pollute your grounds with old coffee. The bean hopper is fragile and if you put things together incorectly and force it, it will break.
I'm puzzled by people who say this won't grind for espresso. I haven't tried dark beans yet, but with medium roast, as I said above, I can choke my Gaggia Carezza without even going all the way to the finest setting. I'm also puzzled by the need for the much-talked-about modification. All it does is remove the detents as you click from fine to coarse; it does NOT allow the machine to grind any finer and in fact if you need "one and a half" clicks, without the mod you can hold the hopper in place between detents while you grind.
When I say cleaning is easy, it does require minor disassembly, but unlike my Solis Maestro, once you take the burr out, this machine lets you get at all of the mess and brush it down the chute easily. For daily cleanup (which is mandatory unless you want poor results), I simply pop out the top burr and run the grinder. The carousel purges itself of 90% of the mess.
Quick tips: if you prefer on/off button operation, just turn the timer part way to #1 and hold it. When you let go, the grinder stops. Daily cleaning is made even easier with this trick: lift the top burr out of its notches and set it down quickly on the rim of its holder. Do this a few times and you knock 95% of the built up grounds off the burr without making a mess. Then run the grinder a few seconds with the burr fully removed, tap it once on the back to move grinds down the chute, and you're done. Takes about 45 seconds and ensures a good grind the next time.
I won't insult those who put the top burr in upside down because I did it when I first unpacked the machine. But the cure is very simple: a small screwdriver or butter knife in the slot allows you to rotate the collar and unlock the burr. Awesome design? Hardly, but also not a deal killer, especially for the price. Which is what this grinder is all about -- a serviceable machine for much less money than its competitors.
