Not really lifetime. If you are expecting to have Microsoft office 365 for life at a price of less than $10 US, then you will be disappointed as I was. That is what was advertised. The truth is that as with any grey market software, the manufacturer such as Microsoft will catch up and disable your license. My CJS key lasted about 6 months before it was shut down by Microsoft. For a pricing perspective, that is still a good savings. MS charges $10 a month. I got 6 months of use for $10 with CJS key. If you don't mind buying a new key and reinstalling the software every 6 months, then you will be satisfied. Just don't expect that it is life time. It is false advertising. Oh...don't even bother trying to file a claim with support. I did and all I got was an auto response back saying that they only support cases within 90 days of purchase. So they already have figured this out and implemented policies to get around customer complaints about "not life time".
