I purchased two Microsoft Office 2016 licenses from this company in November 2017. I promptly received my license keys and downloaded Microsoft Office from the Microsoft website and entered my keys. They worked perfectly with no problem. I saved a ton of money. I own a small business and this saved me quite a bit. The two licenses only cost me $110.
I have continued to use the entire Office suite with no problems - even when it comes to Microsoft updates on my office products. I am very happy with the purchase and have had zero problems so far.
