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

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.

We have been using these flash drives for several years, and I rarely have an issues. Occasionally there will be one that just doesnt want to show on the computer, but it doesnt happen often. We order roughly 250+ a year, so I will take 1-3 flash drives that dont work over the course of a few years.

We always used C/Ds and DVDs to store and transmit data. Now the files are so large that flash drives are the way to go....

good storage device

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.

It was easy to use for storage.

So far 2 would not hold 2 GB

good price and quality ,using to send family photos to family members, like idea that covers to drives is attached, would buy again

These are the perfect size for sharing files with friends inexpensively. After the first 10 were used I realized I want to continue to have them on hand anytime I want to share a file with friends and ordered 20 this time. What a deal.

Purchased this 10 pack as a pen testing solution. They are working so far, but writing to the product and conversion to bootable image drives was incredibly slow. Total write time for an image file (ISO) of 16GB was 32 minutes. Not great if you are in a hurry! Port used was USB 3.0, and this device is USB 2.0. This item was not up to the speed of the USB 2.0 spec, claiming up to 480MB/s. In my writing speed test, I wrote a 16gb ISO file. This took an incredibly long time, at an average write speed of 9.7MB/s. The speed decreased marginally, but steadily, as the write process continued. I might recommend for multiple smaller file solutions. Perhaps office documents to home, or schoolwork to home. In contrast, my tests say this product is not up to larger file work like ISO images.
