This user sent me a charge 2. I got the tracker only with someone else's name on the package. It also came in a pouch that said "replacement"
This method involves scamming fitbit using the warranty program, and is dark grey hat at best. It works though and I got the fitbit within 1 week of ordering for it.
All of these Fitbits are generated through "Social Engineering", these guys hack into people's account who have bought Fitbits previously and revoke the replacement. I have heard that Fitbit trying to track the culprits so it is not suggested to buy through this social engineering method.
