I am new to grinding and have been making espresso for only two years.  This is my first grinder and I only intended on spending $20.  Upon investigating grinding, I learned much was to be had in this area and chose the Solis Maestro based on many reviews.  I was still hard pressed to believe I should spend $100 on a grinder.  I was not disappointed.  It came in a simple box, but well packaged.  In excellent condition.  It has preformed wonderfully.  It does everything it says it does.  I only drink espresso, so I cannot comment on how it grinds other than that.

 Upon placing fresh beans in the hopper, you may either place a portafilter under the shute and grind right into it or fill the container.  The button for the portafilter is located right above the shute and easy to use.  If I am otherwise occupied, I will grind into the container instead and use the timer to grind.  Both options work well.  The setting for the timer and grind setting are easy to use.  Cleaning is easy with a soft bristle brush and after the first couple of uses, static was no problem.  I dissassemble occasionally for a more thorough cleaning.  Very easy and very quick.  It sits nicely on my counter and takes up little space.  I forsee a long life for this machine as it is well made and works consistently for me.  My $100 was well spent.

 I am not an expert and only a novice espresso puller.  I hope someone finds this review helpful from this standpoint.  I pulled a good shot before with my mid/low end machine, but now pull a pretty darn great shot.  It is has increased my espresso joy two fold.  My next step will be a new machine...

Bald mountain was quick with my order, even though it was the holiday week.  They sent confirmation emails and offered free shipping.  Great customer service all around.
