Product worked perfectly, as advertised, HOWEVER make sure to READ THE INSTRUCTIONS, Microsoft might require you to go thru a telephone activation process which can be a ROYAL PAIN, and not at all the sellers fault as they have no control over microsoft's poor costumer support.

As usual, works like a charm, my customers are always very happy with these keys

Funciona, muy recomendable

Todo correcto. Fácil activación.

Thank you very much, it worked perfectly – it was easier than I expected!
