Very consistent grinder, nice heavy burrs and a convenient timer.
Negative Product Points
Fair amount of grind retention if not ran empty, static issues with grind holder, and limited steps.
This was my first entry into using a burr grinder, I had for years used a blade grinder for all my coffee needs. Might I say that this was quite a step-up from my old blade grinder, I really couldn't believe it.
I bought the black plastic version of the machine and out of the box I was quite impressed at the time at the feel of it, very solid, and piano like step design that goes across the front of the machine is very appealing. At the time I was living at a house with low clearance on the counter tops and appreciated the small nature of the grinder, I could leave it under my cabinets and easily refill the hopper without moving it.
Primarily I used the grinder per dose, or just put in enough for what I was going to be doing that made the timer feature on the front of the grinder excellent. I could put in my beans turn the timer on and then go about my other steps in making my coffee, which cut down on time. This also ran a dual purpose as if you run this grinder for a few seconds after the beans are down grinding it gets most of the excess grinder out that will just sit inside the chute until your next use. Every time I didn't do this I ran into bitter coffee as a few grams will sit in there.
My two biggest complaints were the limited steps and static issues. The limited step were not really a big issue for my uses, but when I recently wanted to get an espresso machine it meant that I had to also buy a new grinder, with the infinity there are only 24 steps and about 2-3 that would be suitable for espresso, which isn't enough to get the optimal extraction per bean when using an espresso machine. I ran into static issues with the grinder container when I used certain beans, it wasn't an issue that was always present, but would rear it's ugly head every now and again. It just makes a little more of a mess.
However, it is a great grinder for my primary uses at the time.
