KOOTION 10 Pack 4GB Flash Drive 4gb USB 2.0 Flash Drives USB Drive Jump Drive Bulk Thumb Drive Swivel Memory Stick Black

First of all, these are certainly NOT full speed USB 3.0 flash drives. You get an average of about 20 MB/s write speeds. And while you DO get pretty fast read speeds, it needs to be taken with a grain of salt. Secondly, the port cover on these is very flimsy and doesnt do a good job at protecting the plug. Finally, this set of ten flash drives comes in a very basic box and the drives are not individually wrapped/sealed. Its not a bad value overall and I can not speak for their longevity, since I only recently started using them.

I needed Low capacity drives for compatability with usb 2.0 devices. i tested these and yes these are fast usb 3.1 and have 16gb. Authentic -get what you pay for. i copied 16Gb at 20MB/s -reads at 120MB. fast read speeds to play 4k video from. photo of test results attached. good product for cheap affordable price and performance. although i hate the swing type handle. i knew what i was buying and i got exactly what was advertised.

I uploaded photos taken at a Bat Mitzvah so that everybody would have copies. The upload speed was a tad slow for my taste.

They seem to be good for the most part but I’ve ordered these sets a few times, and often there’s one that has some sort of issue and clients have problems accessing the files and it becomes corrupted. Overall a good value for the $. Be sure to format each one and check it before putting files on them and handing them to clients.

I PURCHASED THIS PRODUCT AND ONE OUT OF THE TEN DRIVES WAS NOT WORKING. WANTED TO CONTACT THE MANUFACTURER TO HAVE IT REPLACED OR RETURN BUT NO PHONE NUMBER OR EMAIL ADDRESS

Package arrived quickly and the drives perform as expected

Great purchase for the price and quantity! Very happy that I gave these a chance, even after reading the reviews....the drives are packaged in a slim box, in individual slots...arrived quickly. It was a quick and easy process to format the drive before using (so far I have only used one of my projects). The space on the drive was only 3.74 GB, however - Im super techy so I cant break down the specifics any further. But essential, it got the job done and I am excited to continue branding these with my companys information and providing my clients with their files in an easily assessible fashion.

I probably wouldnt bother to write a review for a multi pack of thumb drives, but I accidentally ran one through the washing machine AND the dryer, and all the photos on it that I really wouldnt have been happy to lose survived. Very fast transfer speeds too.

one in ten did not work, which was predicted by all of the reviews.

Love these had enough to hand out to family with grand babies pictures and my daughters pictures on and still had memory left over for them to add their own pictures on
