Are you going to use it casually or store 'critical' information on it?
If you will be storing critical data on it, I suggest you buy one with advanced protection such as fingerprint protection! I have one fingerprint protected pendrive from Adata. Ofcourse it costly, Rs. 650/- for 1 GB, but its worth for the peace of mind it gives me when I am traveling in crowded trains and buses. Earlier, I used to check every 5 mins if the drive is there in my pocket or not! Besides, its a cool thing to impress your friends
