you get the key right away and the first key i received worked!

Sorprendentemente si funciona :D, solo recuerden usar PayPal por seguridad

It actaully worked. I just purchased the key on website, and then key sent to my mail in 10 seconds.
Activate on my Window 10 through setting and put the 25 keys and it worked.

Compré el windows 10 home y en dos segundos ya tenía mi código para activarlo. Muy encantado!

The first one worked. I know these can be tricky but maybe I was lucky.
