A capable grinder at a good price, but lacks consistency; perhaps best as a second decaf grinder
Positive Product Points
This is a moderately capable grinder at a good price. Despite an all-plastic exterior, it fits together very well with tight tolerances.
Negative Product Points
Consistency. Maestro seems to have a bit of "float" in its burr assembly, so "dot 6" isn't always the same later, even for the same beans.
This is a moderately capable grinder at a good price. Despite an all-plastic exterior, it fits together very well with tight tolerances. A little advice: Consider how much you're spending on your espresso machine with respect to your grinder. You may be tempted to skimp on the grinder. This is a good entry-level grinder -- match it with your espresso machine's capabilities.
Consistency is Maestro's biggest weakness. I started with Maestro and upgraded to Rocky as part of the reseller's "buyer's remorse." Now when I return Rocky to a prior setting, it is the same setting dead-on. Maestro seemed to have a bit more "float" in its burr assembly, so "dot 6" wasn't always the same later, even for the same beans.
Because the grinder doesn't weigh much, pressing the portafilter "on" button scoots the unit. You must hold it with your other hand to keep it stable, defeating the value of the easy-reach button. The button should stick out so you could press down instead.
Hint: Before you take out the burr assembly to clean it, pay attention to how it will go back together. There is a little slot that must line up with a tab on the bottom of the hopper. Yes, it sounds obvious but is easy to overlook.
I've dealt with Whole Latte Love over the phone a few times, and always felt a little rushed. Their tech guru (Todd) is great, but their sales staff don't seem overly knowledgeable about finer points of the product. You will get better information, by far, from this site.
Three Month Followup
I started with Maestro and upgraded to Rocky as part of the reseller's "buyer's 30 day remorse." I understand that the new Maestro Plus addresses some of my original concerns with the original Maestro but I have no firsthand experience.
