It's very convenient, simple and powerful!

FetchRSS works very well, has a rather nice interface, and has a descent pricing structure.
I've tried many others and this is the first one I could tolerate and get some regular benefit from. Well worth the modest fee they charge.
I would steer clear of any free services, period. There is basically no free lunch.
Easiest to use & best paying feed creator out there.
If you want a free option, try the fully free rss creator, not a freemium.
