Strictly nickel!

I had some renowned brands in the lead in seeking a usb key for my friend ...
Little by little, or rather site search site, I came across this key, and despite its color really mat, I ordered it, to offer it to my friend who has a keyring ( to open doors and car) .. It was quite bulky so a USB key that resists all other keys!
This key serves this function in every respect!
Resistant (metal), a hole in the ground to hold on to a key ring, no cap we could lose or forget on a desktop (great when you're not at home lol!) .
The key cut into the metal mass, par excellence.
A transfer rate transmission / reception among rated the usb key market.
It was nice that the manufacturer the comb brighter colors, but basically, it's not what we asked a USB key in the first place ...
In short, I recommend you this key, really.
