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

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 have purchased approximately 500 of these flash drives in the past 2-years, and so far and have been very satisfied. The box of 10 is very well packaged and can withstand the rigors of virtually any shipper. Ive only experienced about a 2% failure rate so far. For whatever reason, they cannot be formatted or read. This is the only reason I didnt rate it a 5-star product. The 98% that are not defective have held up very well and my customers love them! Plan to purchase more in the future.

Worked fine

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

Buy in bulk. Had one dud out of five.

Transferring DVD (audio and video) for family members. Utilized 5 to date. No problems.

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.

Its weird to me that at this point in time, flash drives havent gotten significantly cheaper. Considering that a lot of new computers dont have CD drives anymore, why wouldnt flash tech keep up with that? Regardless, these seem to work well. Its a pretty affordable pack, they seem to be well made, and I havent had a problem with data transfer. This is also one of the few flash drive packs that have quick shipping instead of a month-long wait as they make their way from China, so if you need these within a reasonable time frame this is probably your best bet.

So far they all work properly. No issues and decent price. Not the fastest drives but get the job done.

I bought these USB sticks because the were cheap and had a decent rating. I got less than what I paid for. While they are indeed 32GB capacity, they are absolute garbage. I knew something was wrong when the quick-format to NTFS took over 20 sec. I tried to write 10-15GB video files to these sticks. The write process took 10-15 sec to start then cycled: 16MB/s (3sec) --> 0MB/s (6sec) --> 16MB/s (3sec) --> 0MB/s (6sec) --> . . . . It did this through the whole write. Rather than throw them out, Ive tossed these aside and only use them when I need a give-away USB stick. Thats how Ill get rid of them.
