The connectors are fine. The micro USB returns without unduly forcing my Nexus 10, and in my Moto G.
On PC, the USB write speeds 3 are quite good. In fact, everything depends on the size of files to copy. More a file is, the more it goes fast: 10 MB / s for smaller, and more than 100 MB / s for large.
The plastic cap complexion "pretty much ready" in place once closed, but keeping tabs appear insufficient. A weakness so.
The body of this key is aluminum, but it is "sheet metal" fine enough ... We must therefore avoid the bad deal!
The key is very small, its attachment avoid losing it, and his cap ... It is designed to be carried on a keychain.
EDIT: The fragility of this USB key is confirmed: I just dropped my keyring on the floor, and this is enough to make a "nice" shot trace in a corner of the aluminum hull ...
