A lot of good effort has gone into developing this component, however it is not ready. The author makes good effort in English but his use of it is still confusing (he writes "two" as "to" sometimes for instance), the component's language is half English half Dutch, etc.
Also the database is not well organized, I could not find how to delete the 1,000 or so sample items that come with the installation, and quite a few other small issues.
The developer has great understanding of data feeds, however the user can find oneself in a pickle.
For all developers out there, make a Great free component, develop a reputation and you will get more paid work than you will want. Do not try to make money off free components, or get links etc. A good component will make people come look for you. A so-so one will make people avoid you.
