This does a great job with syncing to one news server if your purpose is to read Usenet groups.
I have heard of some problems with binaries, but I do not use it for that purpose. I sync it and read things at a later time.
This app had two problems with the software keyboard with an iPhone/iPod update (3.1?) which caused posting and filter editing problems. These have recently been fixed.
I wish I could add more servers. I wish I could use regex filtering. But all in all, this has been working well for me.
