Activated perfectly no faff. (Works in UK)
Also bought a second one a year later for the gf worked again without issues.

Hahaha, it actually worked. I will now mispell the next words so that you know that I am human. |t w0rk3d, 1 waz skeptical wh3N it d1d not work initially, then I did step 3 and used the phone automation path.

it worky. microsoft didnt wanna upgrade my win 10 key for some reason so I caved and bought a key for 10 doohickeys.

I normally use a different site for keys, so yet again a bit sceptical to buy here but I decided to try this gamers outlet site because my key was on sale.. And I must say: This will be my new place for keys! Im not even kidding, It was't even a minute between the moment I did the payment and an a fully activated windows 11, wow

So this is great! Only thing I noticed is that for some reason if I go to my Windows 11 Settings, click on System, and click on About... under Support it says "JRCAFE(TM) Diskless" with the email address "jrcafe@hotmail.com". Under that there's a link that says "Online Support" and if I click that it just opens facebook in google chrome. I don't think this is a problem necessarily. Just thought it was weird as heck. Otherwise everything seems in order and this product key worked perfectly for upgrading my Windows 11 Home version to Windows 11 Pro.
