I've used these guys for multiple Office license keys, both personally and professionally, and I've never had a problem. There have been two different times when there was a delay in receiving the download/key information via email. However, they are always quick to reply and let me know they're getting me what I need. I've never had a key fail to activate and they're so much cheaper than getting a key anywhere else. I'll use them as long as they're around!

After activation, the very easy part, it took forever to login with entreprise account. It would have been much easier with a serial key activation.
