Looks promising, but ...
Looks promising since it doesn't have many alternatives. Looks simple to manage and to do the job, but in reality there is no documentation (standard installation guide of all Joomla! extensions doesn't count), no way to get support (not even an e-mail or contact form).
And to top it all, it was impossible to add Dines (items). It just showed cryptic message and that's all. Same story on Joomla! 2.5 and Joomla! 3.1
So considering the current state of that extension, the rating is 1-2 stars,
