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.

Very good!
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!

Just prepare to be nervous and this is a great drive!
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.

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.

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.
