Update April 27: The USB key is attached to my keychain and opens in two at the joint, while on the description it says "very resistant and waterproof thanks to its metal housing." I'm not even served me and she goes to pieces. Quality **** m. I hope the seller will contact me to solve the problem ....
Update July 31:
I finally contacted the seller to send me a new USB key, a single block that fois.envoi in 24 hours.
By cons I would have preferred not to wait 3 more months before being contacted.
Small flat, the hole in the key center is smaller than the previous model, I can not add to my keyring. But I'll manage. Thank you to the seller.
Update on 01/04/2015:
The seller contacted me on his own initiative to offer me the latest version of the key, and it is a little bigger than my version 2, but this time the hole is big enough to go it on my keychain. Much stronger.
I love, you can order this version carefree !!!!!
A big thank you to the seller, it is rare to find a vendor like that who wants to do everything to satisfy you.
