Everything you would expect from RSS reader

The killer feature is of course the google reader integration - full sync so I can read my RSS feeds from everywhere and do not worry about having to mark them read again on different computer. Actually the free version has all functionality I needed. Nevertheless I bought pro version (3.99€) just to show developers my appreciation. And I might be interested in tweeter/instapaper integration (only in pro) later.
I have tried oh-so-hyped pulse reader and it didnt even come close to feeddlers functionality.
BTW: the last update making Unread button permanent across sessions and showing only folders with unread articles is awesome!
