This grinder works so good I decided against getting the Solis 177.
Positive Product Points
An excellent burr grinder for beginners and intermediate types.
Negative Product Points
The chute clogs up on occation and needs to be scrapped clean. You'll notice it when it happens because the motor bogs down.
Now available at Costco for under $25 this is an excellent compromise between cheap blade grinders that actually scorch the beans in the process, and the more expensive conical burr grinders, which are the best. There are several variants of this model. Some have a timer and others have a push button that needs to be held down continuously. When I first tried mine, I couldn't figure out why I was getting a course grind when espresso was selected. Turns out the hopper is threaded and still had one whole rotation to go before being fully seated. Now it works great and produces a fine enough grind for a Krups 4000 and a Solis SL-90.
I paid $47.00, but this product is now available at Costco for under $25.00.
