This is definitely the easiest-to-use, simplest-to-understand and prettiest-to-look-at notebook battery monitoring tool I've ever had the opportunity to use.

Its display assists in understanding and tracking the health and vitality of a notebook computer and recently helped me troubleshoot an issue I was having with the sleep mode of my MacBook Pro. With the recent addition of a session-saver it's an invaluable tool on my portable machine.

The developer is particularly response and helpful.
