I thought I was buying a standalone… I purchased a version of office 365. Could not get it to install right on my pc. Contacted the seller about this, they made it right by refunding me the cost of the software.

Impeccable transaction Impeccable transaction. I had doubts and took the risk but it's all really worth it. Transaction is fast, download is well a few Go to wait for, software package works, mounted image works, key works, Office works! Thank you.

Invalid Key, No Response Key was invalid. It happens, no big deal. However, I contacted them multiple times for replacement key and never got a response. Edit: After several attempts I finally went through with Paypal refund. Seller did provide refund at that point so I did eventually get my money back.

Very good price and very fast Very good price and very fast. I received my activation keys from Microsoft in a few seconds and they work fine. Works perfectly in my language and my country.

Legit Keys for Legit Products My daughter's W7 notebook decided after 6 years that its license was no longer valid. No amount of reinstalling and attempts to activate online worked. After buying a key from KeyHeaven, I was able to install the new key and successfully activate it. The price was unbelievably cheap. So cheap, in fact, that now that her PC is back to 100%, I just bought another key for Windows 10. We'll do an in-place upgrade on her computer in time for W7 EOL. Great stuff, KeyHeaven. Edited to add: W10 Pro key purchased and successfully installed. Two out of two trouble-free purchases. I'll happily buy from here again.
