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.

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.

An innovation worth investing in
Impressive device with amazing modularity a very flexible platform which makes it practical for any use. Secondly you don't need any software to start using the drive. The dual connectivity makes it practical for all devices. It is fast so you won't waste time and you don't need pesky adapters. Excellent portablity.

Works with iPhones.
Got this for my iPhone 16 Pro Max to backup some stuff. Works perfectly well and is quick. Yes it gets hot but doesn’t stop working. Just transferred 114 files up to 3GB total and worked fine. Great item it’s tiny lightweight and great value for money.

Good storage but hot in touch
I’ve been using the 128GB Ultra Dual Drive Go USB-C Flash for a while now, and overall it’s been excellent. The transfer speeds are impressive. It’s very convenient to switch between devices with USB-C and USB-A. It feels well-made and reliable for everyday use. The only downside I’ve noticed is that it can get quite hot during long use, but it hasn’t impacted performance so far. It’s definitely good value for the price.
