This grinder produces consistant results for my needs. I grind very small amounts of drip daily, and can dispense directly into a small filter. Cleaning the unit every few weeks with some rice and a brush has kept this working good as new - or in my case, slightly used.

There is only the smallest amount of grinds left inside the machine between uses.

I purchased this unit as a demo from Sweetmarias.com and have been very happy with it. It is quieter and more versatile than the previous Solis unit I owned. There have been no bean sticking issues that other reviewers have mentioned for me, but I grind only a few tablespoons of non-oily beans at a time. The range of grinds I use is limited, so I can’t comment with authority on espresso or press pot quality. I can say that the grind quality is consistent and the wealth of settings provides a lot of fine control.  
Having two controls (one timed, one hand held) for grinding is convenient. Cleaning is a very easy disassembly including the burr wheel.

Sweetmarias.com is an excellent resource for home roasters and I was lucky to have found a demo unit. They have always delivered as promised.
