I was unsure about paying for a product that supplied 5 licenses for such an expensive product at a bargain price. However, my skepticism was unwarranted as I have installed two new installations of Windows 10 Pro and upgraded two Home to Pro versions using the 5 license key.
I will return to this vendor for other product licenses as a totally satisfied customer.
