GIGAwoot Flash Drives by Gigs 2 Go (8GB x 4)

Anybody know whether these are USB 2.0 or USB 3.0? And what about the quality?
I’m not able to find neither specs nor condition on them.

Any input would be GREATLY appreciated!

They’re USB 2.0. I’ll add that to the sale.

If a bit cheaper, these would be good to give to the police after transferring security camera footage from the dvr.
