My first key didn't work, the support helped me out with giving a new key twice. With the second key I waited 8 days because I didn't notice the message. Not sure if that's the reason why the second key didn't work, but I guess the keys expire fast.

Funziona alla grande!

Really quick support, helped me with the key within minutes and then the key worked perfectilly!

Worked fine first time. thanks

I was a bit cautious at first, but it worked totally fine on the first try ! Great price, very good deal.
