I have not heard of them, but decided to do some internet checking.
TravelSafe is a Pennsylvania company that has their travel division out of San Diego, it appears.
TravelSafe's Better Business Bureau report can be found here:
http://www.sandiego.bbb.org/commonreport.html?compid=20004963
Travel Safe is owned by the Chester Perfetto Insurance agency, and their BBB can be found:

They appear to be underwritten by Stonebridge Casualty Insurance Company, Columbus, OH (for CO, MI, MN, NY, VT) and Monumental General Casualty Company, Baltimore, MD (all states except as otherwise noted). their BBB report can be found at:
http://www.baltimore.bbb.org/nis/ne...5298&ComName=Monumental+General+Insurance+Co.
Both Stonebridge and Monumental seem to have satisfactory BBB ratings. The two companies are a part of the AEGON Insurance Group:

Bottom line, I don't know about their coverage, and you can ask them for references to call. TravelSafe appears to have only 2 complaints against them that have been resolved out of I don't know how many customers. Their parent companies several generations up, have good standing with their state's BBB.
Other than that, I can't find much on them. Sorry.
