I like Ultimate Feed Display because you can show multiple feeds in a nice and compact way.
Feeds open in popup, visitors don't leave your site.
Lots of customisation in settings possible.
And when you need support Stergios is always there!
Easy installation. Regular updates. Good support when you need it.
Safety first. I find it a comforting thought that RSFirewall is watching as my clients work in the backend. You can set that modules or plugins can NOT be uploaded.
I'm happy with RSFirewall!
