Detailed Commentary
This grinder is being used with a Rancilio Sylvia, a machine notorious for its strict gind requirements.
The Infinity has come through rather consistantly during my 2 months of use. Here in Japan good espresso is nearly impossible to find. Few barristas of the numeous Starbucks and Tulley's seem to know or care about how to make a real espresso. Happily this was a great excuse to take matters into my own hands.
So, through a stroke of pure luck, I found a Rancilio Sylvia at a second hand shop for 2 man (185.00 US). The shop thought it was broken. It is a 220 volt model, and Japan is a 110 volt nation. One step-up voltage converter later I thougth I was in business. Yet, since home espresso here is practically unheard of, I found few places who could grind to my needs.
Enter the Infinity.
Though rather loud, it has brought real espresso into my life again. The grind can be dialed fine enough to jam my Sylvia, yet it makes no dust.
The only real negative so far is that I have to clean it frequently to get rid of old coffee grounds. Not really difficult, but when I put it back together after a cleaning I have to dial it in again. The difference is only either one notch up or down from its pre-cleaned setting, but boy its irritating to loose that one or two shots in the process.
Also you have to be careful how you re-seat the top bur after cleaning, there is no way to keep you from re-seating it wrong. The result for me was an inability to get a fine enough ground. Easily fixed by re-seating it to its proper position.
Buying Experience
1st Line was great. They sent it to my sister in San Francisco and she mailed it to me.
