I was reluctant to buy the win 10 pro key on this shop and for this (so chep) price, but now i'm writing this review to ensure you that it worked and this is a safe shop where to buy at least this key
According to the service, the other reviews and my good experience, i except that the shop is very good for all the other stuff

Received the key immediately, no problems activating. Great thing, thanks!

I bought a Retail win 10 prof. key to upgrade my OS Win10 from Home to Pro. Within a minute after payment my Key was already found on the site in my account. After entering the key in my PC, I had to update and restart my OS a few times before my Upgrade was activated.
My key worked

I've got the Win10 Pro key immediately, great service. Would recommend everyone.

todo me ha ido bien la clave a la primera
