Great that it allows you to edit meta data for articles, categories and menus all in the one place.
Ease of use
The component is well thought out and quite intuitive to use.
The few questions I've had have been dealt with very quickly and bug patches are made where issues are identified and new features added.
Covers the functionality at a high level but not really needed as mostly the interface is intuitive.
Value for money
License fee is on a fixed month basis - so updates limited to time you have purchased.
