SanDisk Ultra Dual Drive m3.0 USB 3.0 Flash Drive 128GB (Smartphone storage, USB stick, memory stick with reversible micro-USB and USB Type-A connectors for Android smartphones and tablets)

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.

Does what it says, well pleased. Didn't realise it was that small, but that's actually good. Now just to find a very small plastic box, to fit it in for safety. Reason, it will take 5 different series with all episodes, ie POI, GOT, Discovery, etc, and all otg. Happy!

Bought the 64GB version. Great capacity and great speed - technically, this item is a dream to own - but I found myself thinking of this as somewhere between a three and four star item for reasons I thought would never matter. The first is the 'sliding frame' used to expose the USB port either side. I found that it was all to easy for it to slide open in my pocket exposing the microUSB socket. Having had other items with such microUSB sockets break in the past, this makes me nervous. Sticking with case design, the sockets are very exposed. Loose grime and dirt seem attracted to not just the sockets themselves, but to the voids in the sliding mechanism (e.g. either side of the USB sockets). This is not a USB drive that can live in the bottom of a bag or satchel. Next are my old man problems with the drive. I took it out-and-about to get photos printed in a hurry. I lost it on-and-about my person at least five times before deciding to keep it in the zipped change pocket of my wallet. That solved transport - and I was impressed how easily it fit there - but when I took it out to attach to the photo kiosk it felt like it was one ill-timed 'ping' away from flying across the chemists and lodging itself under a shelf of embarrassing items! For someone with smaller fingers I would imagine it would be less of a problem, but it felt very small and very slippery in hand. Added to this small size is a slight feeling that it is not exactly the most robust drive out there - there is an uncomfortable level of resistance plugging it in to a USB 2 slot. So I can't fault the thumb drive for speed, or the utility of the two sized USB interfaces. Capacity is great. And it's so tiny, if you did need to conceal a large amount of data somewhere it would be difficult to find, this would do the job perfectly. It's just a little smaller than I'm comfortable with. Overall, however, great drive.

Brilliant for what it's designed for, but I mistook it for a usb A to C when it's a usb A to Micro usb.

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.

I use this to store my FLAC files to play in the car. It was simple to transfer them from my network drive and there is still plenty of room on the drive. Its shape makes it a bit awkward to get into the USB port in my car as it's under the dash but that's not a great problem. It's also slightly awkward to get the standard USB to keep out when inserting the drive but, again, not a deal breaker. Being SANDISC I trust it should be reliable.

Is my second one. The first broke . It is not that sturdy. Big plus for the small size.

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.

Usually I just transfer via Bluetooth but on large video/photo files that is not a great time saver! So, for my 3d camera I got this and transfer speeds are fast and it's just so easy to use. I tether this to my camera and it's always where it needs to be. Gripe - the skeleton case that surrounds the USB side should have been more robust as the one I have has cracked and although it has an inner aluminum cage affixed, I'm moderately concerned that the tether connection point may fail. That said, the device itself is quite good, like anything else over time a few enhancements are always good!

Very speedy delivery. Item works.
