Has anyone here used Rebtel at all?

I’m going to Europe, and it looks like a cheap way to make international calls from a mobile, to a mobile. They give you a local number to call, then connect you via voip ( I think) to a number you’ve preselected in Australia.

Are there any other companies that do this? Any bad catches to using this kind of thing?
