Used the Phone Activation and everything went great.
I only wish Microsoft was as easy to use as this site ... that was a LOT of numbers for an activation code.
Just remember to tell them that you installed it on ZERO other computers, and have a pen and paper handy to write those numbers down when the automated voice reads them off ... "she" said they will work in the future if you need to reauthenticate the software (with the key that you purchased).

PS. Do not forget to remove Office 365 first if your computer comes pre-loaded with a "free trial" or the new office will not load.

Product (MS Office 2019) activated via website without issue. A bit cumbersome to type in all the numbers for phone activation but it worked.

First Key was blocked but was provided another one which worked activated fine. Thanks

Product is amazing and works! Support is great as any issue is solved immediately great sellers and good reliable product

The key didnt work. I contacted support and they sent me a new key. This time it worked fine and fast. Good service, thanks.
