This is a nice piece of software and does exactly what it claims to do. I bought it just before Snow Leopard was released but unfortunately SL broke RAIDMonitor 3.
An update was quickly released but I still had some issues with it so I contacted the developer and I can only say that his response to my problems has been quite outstanding. With some cooperation between us and, I am sure, a lot of hard work by Aaron, the issues have been resolved.
This is support at it's best and makes the shareware fee worth every penny.
