He posted he would be up and going by this past monday. Put listing up, and now has not logged on since the 6th. He made a post on reddit yesterday that he was taking a vacation making no mention of the status of the orders already placed. Beware. /u/QuantikXanax has yet to officially comment on it either.
Edit: He also said he was taking a vacation to "up his game" which is would make it odd that he wouldn't ship orders placed as soon as he put up listings.
They have quick responses at QuantikUSAadmin@sigaint.org
