I installed this extension and bought the Pro version off of the author's website, and I think everyone should do the same. Why?

-The extension is responsive and always updated
-The author is extremely friendly and available. After I upgraded, all I needed to do was use the built-in contact function to ask the author to enable the upgrade across browsers and OSs. Each time, the author upgraded the extension within hours.
-It looks nice, and is customizable.
-Alerts! Very helpful when weather is changing.

In short, it's a nice extension that does what it is supposed to do, looks nice, and the service is worth paying for.
