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

I am very happy with these! I have used most of them several times, formatting them and writing various Linux flavors and Win10 plus various files and mp3s on them. They have always worked perfectly with no issues ever, so i would not hesitate to buy them again. Good value!

With these flash drives I add a short lanyard to add a touch of color and value added when I deliver my products to my customers

They work well. It is easy to monitor if they are active on your computer; the whole drive lights and responds.

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.

Bought these to use with my embroidery machines. Great buy!

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.

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

Ive purchased these several times and they work great - no issues. Im cheap and while I dont like the slow USB 2.0 writing speed, theyre perfect for my needs.

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.

Order shipped fast and is exactly as described. I have more than enough storage for my files now! I haven’t run into any issues, and I recommend this product to those who are looking for a good set of USB drives.
