Excellent finish (hull of a block, solid, very reassuring and texts / logos engraved) and lower (see photo)! Perfect for transfers between machines / devices or store some data, but it is of course not intended to capture pro videos in real time. Decent performance for general public use (measure USB3, Blackmagic Speed Test) write 5 to 15 MB / s read and 30 to 110 MB / s (depending on files, test with a large 2 GB and 1000 GB of a small total). The connection is not fully protected, but it is better (no nozzle / cap that can be lost) without compromising reliability. And a USB key is not intended to be trimballée beach (sand and water)! Very good!
