The UI is a little funky. But it does what I expected it to do. Never had any problems with it, and have been using it ever since Cocktail went shareware. But don't go pressing buttons and trying every feature unless you know what you're doing. Know WHY you're running a command before you do it. This program seems geared for more experienced users, and does not come with many warnings and "Are you really sure you want to do that?" kinds of prompts.
