KOOTION USB 3.0 Flash Drive 5 Pack, 16 GB Memory Stick with LED Indicator Swivel Thumb Drives for Data Storage (16 GB, 5 Pack, Black)

Please see my photosI bought these as a cheap means of storage to share home media files with family members, in that sense they seem perfectly fine.By looking at my photos you will see that a single large media file copied from a fast NVME drive, with the stick connected to a fast USB 3 port, has a maximum and sustained 15.6 MB/s transfer.When that file is then copied back to a different NVME drive you will see that a sustained 105MB/s transfer is possible.Of course that would be dependant on your hardware and copying many small files will change that speed radically.The USB sticks are well made, all five working as expected. Their swivel tops are great, to offer protection as needed.They have a soft grip type feel and locate well into a USB port.When first plugged in, and formatted to NTFS, their capacity is 14.6GB.Overall they work well, with the expectations of the slower write speeds, but faster read. That seems quite typical, especially considering the cheap price.The only small consideration is, there is no size indication on each drive, not wording at all. So I have marked each one of mine as having 16GB capacity, as I keep them in a mixed box along with others.So, for our intended use the yare great, work as expcted and are a very good price.Recommended.I hope this has been helpful.

Just what I needed I needed a USB drive that was bigger in storage

These are not the fastest USB sticks around but good enough when you need to sell or giveaway photos or videos. Good value for money.

good budget USB keys - used them for various OS installs

stored wedding photos and vidio worked fine

As to service and price.Not yet used

I've now bought 3 sets (of 5) of these at different times. The first two sets worked as well as expected for inexpensive USB 3.0 drives (as evidenced by Crystal Disk Mark). The last set was quite different. Read speeds were slightly down, though not a lot, however, write speeds were very much worse—for small files an order of magnitude slower. This admittedly small sample would suggest that what is inside the sticks by way of controller and/or memory is not always the same so that it is pot luck on what you get for your money. Having said that, I bought these with my eyes open and they will do what I want (archived OS installers), provided of course that they don't also have problems with longevity.

Good for intended use, one failed of ten with a temperamental connection issue.Still presents good value for money. I'd purchase again. Thank you.

Schnelle Lieferung und einwandfreie und schnelle Übertragung der Dateien auf den Stick und andere Medien haben mich überzeugt.

Funktionieren bis jetzt einwandfrei.

Clé utilisée pour faire de la sauvegarde, Très bonne clé me convient parfaitement design et rapidité. J'en commanderai surement une autre.

Bien recibido, bien empaquetado y tal como se describían

Für den Preis kann man nichts falsch machen.Auch die Geschwindigkeiten sind wie beschrieben gut.
