I purcgased this pendrive 5 months ago. Initially it was giving a good copying speed but now it doesn't give more than 2mbps copy speed and also its outer cover is made of plastic which also get broken so now pendrive does not fit to usb port. Also sometimes during data transfer, it hangs and we have to start copying again. Its look is nice with small size but I would not recommend this pendrive. Also, windows boot is not possible in this pendrive as I have tried every method of booting wundows through pendrive. May be due to all these reasons this pendrive is cheaper than other. Not happy with pendrive performance. Purchase it at your own risk. Also service of sandisk is not very good but its easy to install this pendrive on PC. It does not have much features but it is easy to use.
