Flexible, dependable, good customer support

I’ve looked into so many RSS plugins and used a few over the years. This is the best I’ve found. It’s not free but you get what you pay for, and this plugin does everything I need for a very large multi-site. The UI is straightforward, it works as advertised, and the couple times I had support questions their support team was helpful; they even logged into my WP backend (securely) to resolve an issue. This is how WordPress plugins should be developed!
