Working great for me. (I'm now running Snow Leopard, v10.6.1, but my opinion has been the same under previous Operating Systems.) One of my few "must-have" utilities as having a very-large number of clipboards (the "history") along with selected clips just being a keystroke combination away (43 per "archive") provides an enormous enhancement to my Mac. I readily recognize just how much worse off I'd be without this utility.

As for the complaints posted regarding the User Interface (UI), I--for one--find it works well and appreciate that the developers have listened to feedback regarding the alternative presentations of the saved information and given users the flexibility in the Preferences to choose which they want shown and which means (e.g., menu bar, Dock, palettes) to get to it.
