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

I did not have the problems others have reported with some of the sticks not working. As for the size: space for the file allocation table, binary conversion, and format overhead (among other things) cause this to happen. An in-depth explanation would require knowledge of advanced mathematics and binary, so, just take it for what it is.

You will be sorry if you buy from this company. Over half of the USBs will not format correctly and have to be thrown away. Huge waste of time and expense. DO NOT BUY!!!!!

Small, compact, and easy to use, these are great thumb drives to keep around for clients who want copies of their digital photographs on a drive without spending too much money on a large drive. It only holds 32gb so I dont recommend for high res video content.

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!

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....

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 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.

Not my favorite form factor for a flash drive, I like a snap on cap, but I knew that going in, so no complaints. Having had problems with flash drives in the past I did a disk check on all 10, then a quick format just to make sure they would work on my system and they came out gold, no issues. At this price when Ive giving someone pictures or whatever, I can just give them a flash drive, not burn a bunch of CDs or a few DVDs and hope they have a optical drive. Im cheap, but for $2.50 each I can give them away. Only reservation is there was no speed class noted like there usually is with SD cards so I dont know if theyre fast or slow.

Ive been using these as give aways for images and information patients can take with them to other physicians. Working fine so far

This was a good deal, they work great and seem to last as well.
