Good product. Great speed. The dual feature is very useful, so you can connect the same piece to both mobile and PC(only one connection at a time). Price is OK. Worth buying. The slider that is used to move USB and OTG port is a bit hard.
I have been using this pendrive for more then three months.
its amazing.
Pros:
1.Dual USB Drive: can be used as OTG and USB 3.0
2.Speed:in usb 2.0 its about 30 mb per sec and in usb 3.0 about 150 mb per sec.
3.if you have issue in any sandisk product then they have replace your product without any questions
4.Ease of use
5.Economic pricing
6.Stylish look
7.Copying to harddisk via USB 3 I couldnt even take a screenshot.
Cons:
1.there is an slider in pendrive it can move to usb to otg easily .
2.its heating littel bit.
I used SanDisk to copy files from Phone to USB and it worked really well
