Review: A brilliant little usb stick - I bought this to put some films on to take away with me, so I didn’t have to take up space on my iPad. It works brilliantly and fit loads of movies on so I was spoilt for choice. It’s small enough to fit in a small pocket and can be used with a standard usb as well as a usb-c port. It took minutes to transfer all the movies onto it and it loads up immediately when playing with no glitches. A good value buy.
Review: A fantastic, sleek device to transfer files quickly and easily from mobile to laptop/PC. - Excellent drive, superfast connectivity and transfers. Connects to both (as described) to USB-C (mobile) as well as USB-A drive (laptops/PCs). Fits easily anywhere (not a bulky drive) and does not need much space (sleek device). Solid build and format capability, and works well with both windows and android instantly without any hassle. Great to transfer personal files such as photos and videos immediately from the mobile to save on space. Have tried on two different mobiles (Samsung and OPPO) and both mobiles connected seamlessly. My only additional observation would be is to make sure OTG is enabled in settings on mobile before plugging in (e.g. OPPO mobile needed this one additional security step before recognising the drive, the mobile turns this feature off after about 10 minutes - great feature to have for security). Great value for money and functionality. I could connect this drive to USB-C on laptop as well (if available - please see image with drive connected to USB-A, USB-C on laptop). A fantastic solution for anyone looking for an easy solution to save disk space on mobile and easy transfers of files from a mobile to a laptop/PC. Would definitely recommend.

## Questions & Answers

**Q: Does anybody knows actually the real writing speed for it ?**
A: It is around 2.55MBs, which takes forever and the drive gets really hot, to the point I am worried that it might melt down. Better stick your phone in the freezer while it is copying 100GB worth of media.

**Q: Is the outer shell plastic or metal?**
A: its plastic, but a hard plastic. i got one cz i have macbook and a pc. this thing is tough as nails, i have it on my keys and they are thrown around the place. its a good buy !

**Q: How long is the usb C plug. I have a rather thick case on my s9+ and there is restricted access to the usb port. The plug would need to be 8mm long**
A: Somewhere between 7 and 8 mm - silver bit, but black part is tapered so it might still fit ?.  However, suggest you look for a usb-c extension lead (or male to male & a female to female connector - I use both that work fine together) that fits, so as to solve the prob for all.

**Q: dos it work on play back on a galaxy tab for play back**
A: Yes, you can access it like a normal drive.
