Used it a few minutes and immediately bought it. It's so easy to use and has a great, intuitive interface. The number of useful things this program does for a mere $8 is astounding. If you use iCal intensively, this is a great investment for a very reasonable price. A must-have.
Very flexible and effective tool for searching iCal and making batch changes to events. Quick response from the developer when I reported a problem with date formatting. Altogether a nice bit of software to have and to use.
