I agree this is a great tool. We ran a lot of tests and simulated several disasters, all of which we recovered from. The interface is not entirely intuitive. For example, the only way I found to rollback a single transaction was to right click on the transaction.
Brian points out that foreign keys might have to be dropped when restoring information. To that I would add that you might need to disable triggers to properly restore the data. Small potatoes considering the value of the recovery but should be kept in mind anyway.
