Most torrent premium doses are fake - we have actually never seen a real one in the wild. People have created them to gain status with a premium posted dose or to claim they have a complete collection. Dont expect them to work hardly, if at all.
They are also absolutely NOT LEGAL. We own the I-Doser trademark name and copyright, and often bundled with official doses. Doesnt matter if it's homebrew, it is dilution of brand and we will (and have) taken legal action. I-Doser is not an open platform- its our way to control quality and make sure you get the best we have to offer.
Short answer - buy the doses directly from us.
