staggering the size of the key

I think I do not see how it could be smaller, to give an idea, it's no bigger than a € 1 coin and thick as two parts. The USB portion (socket) is twice the key part.
Once connected, it 3mm spring.

For loading speed mentioned by some, the files I use are so much lighter than it really is completely anecdotal. I use the keys for working files, not to put too heavy things.

When the branch, the computer recognizes it immediately and it works without any worry.

I regret as others no strap (for the price that said, it is ok) but I like the hole in this regard. Both the size is an advantage as it has to fast super paumer a key of this size. One can make a cord of a mm.

So good product, when I think of my childhood floppy disks that supported some bytes and when I see that, I'm sick.
