I bought a Windows 11 digital license about 2 months ago and it worked perfectly. It was a retail key (not OEM), so it’s fully transferable. I’ve already swapped motherboards once and it deactivated for a minute, but I just reactivated it online with no issues. Keep in mind OEM/digital licenses tied to the original hardware = usually not transferable, The one I got was Retail keys = transferable between PCs, its way cheaper than Microsoft’s price and activated instantly as a Windows 11 digital license. No watermark, no activation problems even after hardware changes. More on reddit.com

I've been through the ringer with the grey market key sites. Had lots of issues with the keys working but then they'd get deactivated all of a sudden. So I went down a bit of a rabbit hole. From what I learned, you want to make sure the key you get is Retail and not OEM. These OEM keys are so cheap but they actually aren't supposed to be sold. They are for the manufacturer to put on their computers. You can still get a Retail key pretty cheap though. I use DigitalChillMart now, they're the only site pretty much that will sell you a Retail key for a reasonable price. More on reddit.com
