Fantastic control of grind, great consistency, easy adjustment between espresso and press/drip.  Small size easily fits under cabinets.  Timed doserless grinding is fantastic.  Well built.  Easy to use.  Customer support is superb.

The display would blank out occasionally, but the grinder continued to work normally.  Baratza quickly sent a replacement when I contacted them.  The unit now works flawlessly.  That's the only reason quality is a 9 rather than 10.  Otherwise the machine is very well built.

I finally took the plunge to get a Vario two months ago when it was clear the Virtuoso just couldn't cut it for consistent espresso.  I thought I'd need to get a Mazzer, but was really dreading having that conversation with my SO, not to mention  not being able to slide it under the cabinet without removing/altering the hopper.  I was ecstatic when I first saw the Vario, since it seemed to meet all my needs (espresso-quality grind, small, SO-friendly, dual-use), but was a bit skeptical that it would really work as advertised.  All the chatter on CG and HB convinced me to give it a shot, and the Ian and Meg at Stumptown were awesome in answering all my questions.  I've put about 10 pounds of coffee through the grinder so far.  It is a great machine.

I've found the use of a funnel (cut down yogurt container) reduces, but doesn't eliminate, the spraying of coffee when grinding directly into the portafilter.  Grinding into the container rather than directly into a portafilter eliminates coffee spraying, but I find the funnel a decent compromise.  

I move my grinder around a lot for cleaning and to minimize the counterspace consumption when not making espresso.  Sliders for macro and micro adjustment are easy to move unintentionally when moving the grinder--not a big deal, just need to be careful and note where the sliders are for your beans that day.

The folks at Stumptown Annex were awesome, plus they threw in a pound of coffee.
