My mind never wonders what it would be like to own a better grinder - this one is that good.
Positive Product Points
Liberal grind adjustment makes this a great general purpose grinder. I find the repeatability of grind is adequate, especially for this price point. The Maestro is quiet, looks good on the counter and I can grind straight to my portafilter. The timer switch is a great addition when I'm not grinding into the portafilter.
Negative Product Points
Static electricity is the number one complaint I have against the Solis Maestro. It's also the only serious fault I find. I often wish it were a bit heavier as it slides back when I try to press the front mounted grind switch without first backing the machine against the counter back.
The Solis Maestro is my first burr grinder. I've been using it now for 3 months to grind all my home roast beans. Before the purchase I did what you're doing now, I read all the reviews on the Maestro and others. My decision to buy the Solis and not one of the other grinders in this class was based mainly on what I learned in the reviews. Namely, the Maestro is a really good grinder at any price and at around $125 including shipping it's a Great Bargain. I have not regretted the decision.
I have used the grinder to grind at both ends of the range, French press to espresso and lots of drip. While my experince with espresso is limited I can certainly say I am NOT being held back by the Maestro in developing by skills as a barista! I'm grinding 3 clicks west of the portafilter logo and getting lots of crema - and Loving It!
My only real complaint to date is one you'll see mentioned in nearly every review of the Solis Maestro - static electricity which can, given the right conditions, literally blast ground coffee out of the collector bin when you pull the bin from the housing. I've actually gotten coffee blown into my face from the static charge! I like coffee but I don't want to wear it! My solution (paritial solution) has been to use a little tool left over from my audiophile days in the early '80s. It's a Discwasher Zerostat gun that uses a piezo electric gizmo to generate a neutralizing charge. We audiophiles used them to get the dust to release from vinyl LP's. (I know, all you Gen-Xers are saying, "What's an LP?") This solution is about 70% effective. I simply point the Zerostat at the hopper and "fire" the gun a few times at the all plastic Maestro. Since using the gun I've not had one "coffee dusting" and the bin dumps much more completely without trying to knock the bin on the sides to dislodge the electrified ground coffee.
If Solis can add a bit of weight to better anchor the machine and cure the static problem they will have a classic that you'll have to spend more than double to beat.
