I've been using Navicat on and off for about six months, and overall it's a solid, full-featured app. The schema and data synchronization is excellent. Customer support is also very responsive. The one big complaint I have is with the UI...it sorely needs a refresh. There are very few options for customization, such as font or list display settings. The icons are gawdy, with no ability to use small icons in the toolbar, or remove icons from the toolbar. Otherwise, it works as designed.
