Several years back I bought a new Nikon (brand loyalty - I'd had one stolen, dropped one, this one simply 'stopped for no obvious reason) when I was in KL, complete with a 'global warranty'.
Encountered problems while still under warranty when back home in Thailand, and was informed 'yes' under warranty but 'no' for any service or repair here in Thailand as had to be returned to country of purchase, Malaysia.
Guess that may have been mentioned in the very very small fine print, but rather defeats the purpose of a global warranty.
