I bought this pen drive from flipkart from 560rs.
It is of 32gb.The pen drive supports otg and usb3.0 I used it for 15 days now, I found the writing speed of 40MB per second from my laptop 3.0 ports.
It also works nice with my redmi 1s.
I used it on my micromax full hd led tv for playing full hd movies for 3hrs continueosly without any lag. There is some heating issue also.
It has some security software preinstalled which is nice.
I got 31.2gb free out of 32 gb.
Overall this pen drive is good.
