Have you contacted the company directly? Checked any Better Business Bureau reports? Done any research on the Internet?

I, too, am interested in finding a health insurance company that will protect me wherever I am in the world. So, who's going to do his homework first: you or me?

Will happily exchange and compare notes.

So, come on. You asked the question. You first. Then me. Deal?

I have heard good things but never used it myself. It is supposed to be quite flexible. The only thing is it won't cover you when you work in a country as far as I know.

 I have their travel insurance, though I haven't had to claim anything back so I can't attest to that. When I did my research it seemed the best and the best priced. If I remember correctly they will even send you body home if you die abroad (this was important to my Dad, apparently it costs thousands to get a body home). 

but yes Delphine86 is right, it won't cover if you are working. What is your visa?
