I bought a key, didnt work and sent an email to them. They responded within the hour and were happy to help.
Great customer service!

For those wondering if this is legit, it actually is. At first, my CD key had already been used, so I contacted customer support and received an e-mail with a new code within 3-5 minutes! The new code worked, by the way. You will not find it cheaper anywhere else, and the customer service is fantastic! I do not normally write reviews, but this website and its owners are well-deserving of it! 5 Stars from me!

immediate delivery, worked great

Awesome service, third key bought on gamers-outlet (2 W10 Home retail, now 1 W10 Pro retail), code delivered in 5 minutes, used to upgrade from W10 Home on a Rog G15 laptop to W10pro. Worked like a charm

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
