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

I ordered 2 boxes of 10 just over a year ago. Every single one was excellent! No bad ones, very reliable, steady transfer speeds, burst data rate is really good, large data transfer is very good, Multipleto large amounts of small data file transfers is little to be more desired but not unreasonable for the cost per drive. I used many for Windows 10 installation flash drives and gave to computer sale clients, gave to clients for quick data transfers. I just order my third set of 10 and will use this next set for some macOS install Flash drives. I will continue to buy this product over and over. I actually leave one in my back pocket and sit on it all the time, this thing has not been crushed by my fat A**, lol. Still works today!

So easy to use; there is sufficient space to write on the silver cover to identify each drive. You can copy a bunch of documents, pictures or files, either as folders or continuous individual files. I used one to back up all of my pictures (over 7000!) and still had space for more. At the price, I can afford to create digital files for photos Ive taken over the years and give each of my children one. I did test each one upon receipt; all of them work.

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...

Happy with product. Good quality for the price

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.

Great product for the money

So far 2 would not hold 2 GB

*Every* drive from this purchase failed with unrecoverable sectors on Windows 7, Windows 10, and Mint v21. None of the drives presented errors when they were reformatted (variously to FAT32, exFAT32, and/or NTFS), but all of them failed when trying to read data of various sizes. The drives responded at extremely slow speeds, seemingly slower than USB 1 speeds; I couldnt tell if this was error recovery attempts or just the drive being absurdly slow. (And frankly didnt want to invest any more of my time in investigating...) TL;DR: Dont waste your money on these drives - theyre not worth the cost even if they were given away for free, as they dont reliably store data.

Buena inversión y fácil de usar.

Didnt need large thumb-drives, but needed a bunch at a reasonable price. Needed to be good quality too, because theyre going to be stored away for posterity with tons of data by year. I like them so much Im going to get more.
