I bought this for my mother here. I did not use the insurance while she was here for 6 mtnhs, but gave me peace of mind.
My friend's father fainted while he was here in USA (in Texas). Total check up bill came out to be 45K, but i think my friend said he just paid 2K, rest was covered by insurance. It was not the same insurance that i used, but health coverage do help in case of unexpected situation.
