I give it four stars for handling because the power switch is located on the rear of the unit, meaning when it's in the rack between other equipment, you cannot switch it on/off easily (I am not in the studio every day so switch equipment off when I'm away).
Other than that, I quite enjoy that there is no recall (really forces you to listen and adjust accordingly, rather than flipping through presets). It does require some jack-XLR adapters to be purchased if used with a patchbay (which is the case with me) so I would have preferred the connections to be TRS on the rear but this is just a minor complaint.
Sound is great, didn't find myself using the saturation feature on bus mixdowns (but sometimes on single-track compression/mixing yes) and the two band tone-shaping seems a bit limited to me (I would have liked the option of subtractive EQing too), but again I haven't found it to be a major issue.
