Nice and fast
Nice and fast for the price, cheaper than other places.Had to plug my phone into my pc all the time so i got this so i didn’t have to and i’ve had no regrets, fast and due to small size its easy to put away without thinking of breaking it, can clip onto a key ring as well.

Need an adapter?
I bought this product assuming it would fit both my tablet and my phone as well as having a conventional USB on the other end. It would greatly save time downloading photos from my phone to my PC/laptop. Alas the product fits neither my phone nor my tablet. My wife had once bought an adapter which does fit those devices and has a conventional USB Type-A port into which I can fit the product, but it’s clumsy and has little benefit over my previous method of transfer of files.On a positive side it is SanDisk and thus very reliable and has a large capacity in a small package. Furthermore it is very good value for money.

Very useful
I wish I had bought one of these ages ago. Super handy to have just one memory stick that I can use on my PC, laptop and tablet. I prefer not to have everything in the cloud as I often work in areas with very poor coverage so it’s more convenient to have my files on a USB drive. Read/write speeds are more than good enough for my purposes.

Tiny drive, BIG storage, fantastic!
Great, large capacity, great brand. I mostly use it for copying photos and videos from my Samsung phone for backup and to clear space. Much easier than popping out the microSD card!I also carry extra TV shows and music on this drive to listen to on my phone or plug into a smart TV to play back.Only minor downsides are: the plugs are still open at the ends, so dust can get in there. And the supplied software for the phone is great, but I expected file transfer to be even faster than it is.

Be aware that it doesnât have USB C
Beware! What looks like a USB C connection is actually a micro USB. It is fortunate that inexpensive adapters can be bought easily.
Crystal Thompson –
The product is of great quality but the description never said what phones it was compatible for. It said all androids. Then I seen a newer version and ordered it but it wasn’t compatible either so now I have to send them both back. Where you plug them in isn’t compatible and the pictures don’t show what end it has to know if it is compatible or not. The description says to go to SanDisks website to see compatibility and it wasn’t anymore help than the ad. Not very happy.

Very impressiveI honestly want to tell you all it has a great speed of 40 to 60 mbps on pc and 20 to 25 mbps on mobileI checked the speed in movies transfer from pc to Pendrive.In mp3 or photos it varies from 8mbps to 20mbps depending on the size of file.*It is the best ever sandisk pen drive, and amazon give me two day delivery without any charges.Works fine but heats up a bit.Works great on all otg supported smartphones And it’s USB 3 and not USB 2, so the speed is a good.A lot better than purchasing cheap USB OTG adapter and plugging normal pen drives. But it’s also good to have a OTG adapter in your arsenal since you might need to connect a normal pen drive some day.But the problem is it is very small and so, it heats up pretty soon.Although speed is great and look at the warranty 5 years warranty its good enough.You just have to submit your amazon receipt at warranty claim. If recipt is lost then you can use serial number written on the Pendrive.
