The ability to manage all of our campaigns from one place was very useful when we were managing many different accounts at once with varying budgets & goals across those clients! It's been awhile since I've used their product but there are no significant issues that come up as far as customer service or features go - so it is hard not like anything about them now!! We love using Sitemagic because its made running multiple sites much easier than having each client log into separate systems (which led us down some dark alleys).
