I had the key in 4 minutes
I did install it by using this site https://office.com/setup
Activation works and programs works perfect
Recommendation

Got the key within 20 mins, wasn't sent to my email but was in the 'downloads' section of my account.

Used the key with the linked ISO from Microsoft servers, worked immediately. Thanks!

Highly recommend! It works! =)

Literally no complaints, 10/10

Took 15 minutes to receive but worked great, went to https://office.com/setup and used the key on my account, works flawlessly.
