This plugin adds an enormous amount of functionality to my website. It's easily customizable and already comes with a bunch of different themes, adding locations with a spreadsheet (.csv file) is simple and quick, amd I've had no problems with the plugins performance whatsoever. Loads quick, works wonderfully.
Not only that, but the support is fantastic, Lance does a great job responding to questions and helping out when needed.
Terrific plugin, would recommend to anybody.
