The keys I got at first did not work, but after contacting support they were super quick to respond after just a few minutes and gave me new keys, and they work fine. So I can recommend this, even though it was a little hassle. Can't beat the price.

FANTASTIC AND CHEAP, i will repeat, do doubt

Paid with paypal and got the key via email. Activated instantly 10/10

Product key downloaded and installed successfully. Perfect

The Win 10 pro activation key was sent quasi instantly after paying with paypal. Thanks ! Took care of that annoying windows watermark in less than 3 minutes and 4$ !
