It simply works.
you grt the coad in the websight itself. no need to wait for the mail. but this means you can be confused as well

I bought a Windows 10 Pro activation key and the key worked at the first try. Great deal.

Bought and was instantly available, checked the PID and the key was valid 10/10

works great! first time buying a product key :) this site seems a bit sketchy, but i gave it a try :))) i now have a product key for a Dell Inspiron im trying to sell

Perfecto, al inicio la key que me mandaron no me sirvió pero me contacte con soporte y me mandaron otra con la cual se activo sin problemas mi Windows 10 Pro excelente servicio!!!
