I'm going to visit Hong Kong soon, hut only for 2 days. Since everything is generally cheaper there I will be buying a nikon d5100. I am worried that there might be some issues with it that I will only discover once I leave hong kong. What can I do to test everything that needs testing while at the shop AND when I get back to the hotel? PS. When I say everything I mean EVERYTHING like sound ISO and the whole thing. (I'm a beginner :$) thanks in advance!
Added (1). When I say issues I mean "errors" or "faults" that would require me to go back to the shop and exchange it for another nikon d5100
