I love it!

It works flawlessly. It is not resource intensive so it does not effect my workflow in the least, notifications are very discreet, and it opens the message in a browser window allowing you to immediately type a full reply. If you already have a browser window open it will simply open a new tab in that current browser, without disturbing what you are currently working on.
