There are no labels or markings on the drives themselves and they look exactly like the USB 2 I returned for having them at all didn't work. Probably USB 3 with 16G. After an hour and a half I couldn't upload 3G photos. When I was finally able to partially download one, it wouldn't open. A tiny cheap 16G Cruiser Edge I've been downloading for a while, same data, all 5G in 15 minutes. The only ID on the box was a paper label that said it was 16G USB 3. I seriously doubt all of that. The label said it was made in China, but that's nothing to complain about since most of them are made there.
