Pretty skeptical at first, but actually worked and key was given instantly. Best price honestly, anything lower tends to come from sketchier places.

Windows 10 Pro Key worked! Lisa is an extremely patient and kind person, and will most likely help with anything you need. Best price around for sure anything less is a little sketchy.

What are OEM keys? 2018-03-22T11:50:23+00:00

Definition of OEM:
The term, OEM (original equipment manufacturer) refers to companies that make products for others to repackage and sell. Resellers buy OEM products in bulk, minus the costly retail packaging that comes with individually sold units. The product itself is essentially the same as its more expensive, retail-packaged sibling. OEM products are used in many industries, but are perhaps most prevalent in electronics.
