I had a key for MS Office 2019 on my old computer. Worked great and linked in to the Microsoft network. Bought a new PC. Microsoft would not honor my existing key. Hey, it's a make you pay double game with them. Done an online search and came across CJS CD keys. Wow. Great price and just the key I needed. Got to recommend this company. The purchase was easy. Downloading the key was also easy. Key worked like a charm. So why only four stars? It's just a minor complaint, but the process of installing got a bit confusing. If you are a complete compute newby, you may have trouble with the process. I think CJS would help if you needed it, but I was careful on the instructions and got along fine. But on the Office key, you need to know a bit more than just how to type in the code. That knocks the rating down. If you are comfortable with doing things somewhat differently than normal, go for it. CJS offers CD key solutions at a great price.
