Fast and easy! No "activation by phone" was required during the installation. Activation of the MS Office 2021 package was successful with the received key.

Got 3 Office 2021 Pro Plus keys. All installed well. Uninstall of older version of Office required before install of new. Easy.

I have always had a positive experience shopping on this website. The products are top-notch, and the customer service is always friendly and efficient. I highly recommend giving them a try!
