Quick Review of Cerberux.cc
I have made 5 bitcoin depositis without problems, and the cards have a good valid rate, though most of them are flagged and unusable just like all the other sites. The checker works well and hasn't given me any fake valids-all my dead cards were refunded. Unfortunately you pay for all your dead cards because cerberux is running usual scam of charging for checks. As others have mentioned, some of the bases are being sold simultaneously on other sites, so you could end up paying a lot of money for invalid cards.
NOTE FOR PEOPLE MISSING DEPOSITS: If you don't get your bitcoins, wait a day and login again and make another deposit for any amount and then click history. Then click a bunch of times on the transaction you actually paid for. This is the only way I can get it to fund my account.
The ticket system is glitchy and often freezes the page when you click send. By using different browsers without adblockers I finally got it to work and sent a ticket about the 3 cards missing adresses(photo below). I don't expect a response but will report back here if I do get one. Also, do not waste any money on the non-refundable cards. Most of them have been there for many months.
