Ok, so this is our plugin - we wrote it. And we thought we should write a brief review of our own code:
It's rocks. It kicks ass. It's stable. It's scalable. It's got most everything you need for a base events calendar system. And if you want more - much more - you can upgrade to WooEvents Pro and turn your site into the next Blockbuster ticket company ( with the right marketing power of course :-) or simply sell tickets to any number of events you need.
Go for it!
