I bought this grinder because the Rancilio MD50 that I have is a monster and continually clicking the doser for a single espresso was a pain. I did a lot of research on this site and others and found many favorable reviews. There are essentially two models of the Infinity: the 560 which is plastic and cost about $90 and the 565 which is chrome and cost about $140. I thought that I could survive without the chrome and save $50 in the process.
So here are the details. The grinder in larger in person than I thought that it would be. I was thinking that it would be the size of the blade type grinders that I have seen. It is roughly the size of a Rancilio Rocky, roughly. It is heavy enough that I felt like I bought a good product. There are 16 grind settings, I am very impressed with the consistancy of the grind. I was able to choke my machine on the two finest settings, and have settled on the third for a good shot. I compared the result to what my Rancilio produces and felt like the grinds were similar. Given the cost and the results, this is a suitable grinder for the "cup at a time" folks.
I have posted my process for grinding so that you can see how the grinder operates.
The bean hopper doubles as the grind setting dial. There is a small black dot that you have to line up with the setting that you desire. To install or remove the hopper you have to turn it all the way counter-clockwise. I found that on the finest grind my Bodum Granos clogs. On the second step, I get a shot but not much. So I went with the 3rd finest grind to get a good double espresso. Not bad for a burr grinder.
To grind you can select a time on the timer or just turn the dial slightly clockwise and hold it to grind as much as you want. Once the beans are through you should remove the hopper and the upper burr to loosen the remaining grounds. I generally just shake or tap the upper burr and then reinstall the hopper and run the grinder a little more to get out all of the grounds. This is the somewhat annoying part of this process. If you grind frequently with the same beans you may be able to skip this step and just get the grounds on the next shot.
The cup that catches the grounds has some static, it is plastic so static is always possible. Tap the cup before you remove it to minimize this issue. I also bang the cup on the counter to pour the grounds in to my grouphead.

This grinder is excellent for this price point. It is very consistant and capable of grinding small enough to jam my espresso machine.
