It is the worst USB flash drive I have ever used. When I connected it to my laptop it did not worked and a notification popped up on the laptop screen saying that It Is Not Supported On This Device. Also when I tried it on my computer the same notification appeared on the screen. So it is totally a waste of money as it does not support most of the devices unlike the USB flash drives of other brands.
So if you want to buy a flash drive then the sandisk flash drive will be a waste of money and I will recommend you to buy pen drive of other brands such as Toshiba, Kingston, and Sony.
