Vouch for Glock, very quick and professional trader. Bought an account with L4D for $5, went first because I have no rep and no problems. Good luck in the future.
I am temporarily withdrawing my vouch. Only 3 days after buying the account I was locked out of it by an attempted password recovery which I do not know the secret answer to. And yes, I did change the e-mail and password and secret question AND made a steam support account, but the secret question that is being asked is not the one I set.
Glock replaced that account with another one, which I was very grateful for. And now, after about 5 days or so, I've been locked out of this account too! Simply absurd.
I know there is a disclaimer stating that he is not responsible for the account once you buy it, but beware that the account you buy is probably stolen from someone else and they will just recover the password.
Until Glock can provide me with an account that won't be recovered within a week, I will NOT vouch for him and cannot recommend this service to others in good faith.
