Overall a very high quality and well-made tuner with good features. Slightly let down by inconsistencies in build quality, awkward settings menus, and clunky editing software.
For me the best features are the sweetened tunings, large display, and the (optional) always-on tuning and buffer modes. The ability to plug in and edit basically everything from the computer is valuable if you want to take full advantage of the customisation options, though the web browser-based editing software is rough around the edges.
The pedal itself feels substantial, durable, and for the most part very well made. It's a shame they cut corners with the flimsy plastic menu buttons on the side, and the plastic battery compartment.
