I got lots of pendrive with me but the one that I feel more confertable is sandisk. I purchased 16 sandisk pendrive through reliance digital mangalore. Its a bit cheaper than the samsung and sony products but its ok for me.its been 2 years but its still in good condition.
It heats up a bit if we keep using it for more than half an hour. The build quality is good , its fully packed , strong and hard. It has got a file transfer speed of 80mb/sec. I could suggest you guys not to purchase through online shopping , just go and buy through near by highly trusted shop. Like reliancedigital. Harsha. Sangheta store. «for indians.
