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

So far, so good .... have had for two months and used four of the ten without problems. It is getting harder to find 1GB USB drives for a fair price - but they are perfect for music for plugging into my vehicle or just attach to my computer to hear certain genre ... 1GB is the perfect size. Easy to use and simply to open and close - just slide the sleeve around the USB. The speed of transfer is NOT fast - but acceptable. I havent had any problem with the cover coming free or detaching (someone apparently did). The sleeve is blank and easy to write on. It had no logo on either side (like the picture demonstrated). I also use them for transferring multiple pdfs and docx files of active projects as well as for transferring files between machines. Although limited to 1 GB (by choice), they do the job and work well for transporting files.

Summary: good drives for the price; decent transfer speeds. Details: Main desktop computer is a Dell XPS 8920. System drive is a 250GB SSD. Two other HDDs for data, 1.0TB and 6.0TB. External USB connections are: USB-C 3.1 (rear), USB-A 3.1 (rear), USB-A 3.0 (front). THe transfer speed difference between the front (3.0) and back (3.1) was negligible. Test Method: The test program I use is ATTO Disk Benchmark (freeware). I tried a few different ones, and settled on this one because the result picture was relatively easy to compare to other results. When evaluating results, I mainly looked at the transfer speeds for files size 1 MB or larger. Pros: good price point; good fit & finish; bright activity LED; decent transfer speed. Cons: None. Recommendations: If you buy a pack of 10, remember to test them all in case any are dead on arrival (all mine were good).

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

UPDATE: Found out the things seem to work a whole lot better if you re-format them as exfat (extended FAT.) Maybe some of the people who own USB flash drives from other companies got them formatted as exfat and didnt know? Anyway, I need these as I said below, and didnt realize they were formatted as FAT32; once I re-formatted them they perform as expected. --Original review-- 761 Kb/Sec copying 15,000 files from an 8.1 GB ISO. Bought these because the Kootion 8GB were too small (have been reading that the Kootion 32GB are slow and also unreliable.) Buyer beware! Thought these would be helpful, but NOT if they are so slow!!!!!! Maybe the company would consider fixing this and sending me some that actually perform better? ;)

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

Overview: As described. Experience: Have had no issues with storage or transfer times, Very cost effective. I preferer retractable type but flip is fine for most uses. The flip cover is flat and smooth so you can easily label or write on it. Standard lanyard attachment as well. Best bang for the buck I have found without buying in bulk.

I have bought this 2 times now because I am saving tutorials that are not very long but I wanted them to be separate so it is perfect...

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 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!

Works as expected. 2nd box I’ve bought
