Works perfectly but can I use the key again in case I format my pc?

It worked without a problem! As soon as I entered the product code, my Office was activated! I was kind of sceptical buying this product, but decided to risk it, and was very pleasantly surprised that it went as it was advertised!

Super einfach und schnell.
Funktioniert alles...... Perfekt !

Worked perfectly well. Extremely happy. Just sharing some info - if you reformat your pc regularly, better buy the bind version which is a little more expensive, but you can reuse the key.

Outstanding! It works on the first try. Simply amazing.
