Got this one from amazon during sale at rs 409(16 gb)
Its fully metal construction and feels premium
it can take drops easily and wont break or chip off
its extremly light weight and very tiny
size is such that you wont even notice the small part protruding out of your usb hub
Tested on WIN 7 machine
Write speed: 8Mb/S
Read Speed: 22 Mb/S
FIle was 500 mb in size
overall im happy with its realiablity
The design is practical and u will need the given plastic string to pull this tiny thing off the USB port
Decent product in all
