Bought it just to activate Windows 10 (Fall Creators Update ISO).

Worked flawlessly, 0 issues, not even after connecting to the internet, so the key is legit.

Instant delivery in my case after confirming my paypal payment. Took just a minute.

I was afraid because of the low price, but I recieved the licence immediatly after the payment and it worked. I had Windows Home installed and it automatically upgraded to the Pro version after I introduced the key.

The initial key that i recieved didnt work, but they sent one in the following hour and evrything got sorted.

La clave funciona correctamente, solo tuve un pequeño inconveniente de que mi key la recibi como 4 horas despues de realizada la compra, pero todo lo demas bien

The key worked. Make sure that you input only the key, though. I accidentally left a space in the beginning of the bar that first time I tried and it didn't work. I removed the space the second time and it worked.
