The 32GB storage is large enough for most of my backup tasks...and cost-efficient.

So far, all of the previous 10 KOOTION 32GB USB Flash Drives I've used have been flawless...no problems at all. This is my 2nd batch of 32GB USBs and will continue to order as my needs arise. Very happy with their quality.

For the ones that are working...not bad, I like them. Pretty good generic little flash drives for the price.

Out of the ten in the pack two of the drives failed to show any storage available, one refused to do anything at all (even light up) and two failed and fully corrupted/became unusable when formatting.

-----Diagnostics + Chip info-----

I used DISKPART to clean and format each one, FakeFlashTest and H2TESTW to verify actual storage and CrystalDiskMark to verify speeds.
