Needs frequent cleaning to maintain full range of grind settings.
Large beans will not feed freely from the hopper into the burrs.
Right out of the box, I liked this grinder. It has a satisfying heft and a sleek, modern appearance. The instructions are simple, the operation intuitive.
Its heavy base makes the unit stable on the counter top. It is extremely quiet compared to my last burr grinder (Bodum Antigua). Static is an infrequent problem, and only seems to occur within a narrow ambient humidity range. It has a wide variety of grind sizes, all of which are very consistent.
If you go back and forth between different grind sizes (as I do), you will invariably come across the only really annoying thing about this grinder - you have to clean it frequently or it will essentially become stuck at its coarsest grind setting. Fortunately, it is very easy to remove the bean hopper and top burr, so cleaning the machine is a relatively quick and simple process.
My only other complaint with the Maestro Plus is that large beans do not feed freely from the hopper, so that you're required to shake the machine or poke the beans into the burrs (CAREFULLY!!!) manually.
Overall, the Solis Maestro Plus is a major step up for me, but there is still definite room for improvement.
Great communication, free shipping on the Solis, fast delivery - what's not to like? Coffee Bean Corral is TOPS in customer service!
