Mkskeys Reviews 

Keys were invalid. Unable to obtain valid keys or refund from the vendor. Have reached out on 5 different occasions with no response.

I have been with Mkskeys for five years now. Every key works and all legal for a great price with friendly & professional support. I will only use Mkskeys. Thank you very much & You earned ⭐⭐⭐⭐⭐

you responded to me quickly as i have written to you. than you for responding to me.

I was thrilled to be able to purchase the key for a 2014 laptop that had been left sitting unused for almost 9 years. Price very reasonable and received key immediately! Laptop running great!!

Never got the final information for the download of the software

As advertised. Great price. Easy download/install.

Took a while to get the software installed but great follow-up from the technical people throughout the process.

Terrible. The keys do not work. I have asked for credit. Crickets. Do not buy from these people

Very reasonable pricing, very fast delivery. The first key they gave me however did NOT work. They quickly fixed the problem though and sent me a working key right away!

This company aims to please! I had a problem and they worked with me until the problem was solved. I would definitely recommend!

They took my money and ran. Their complex activation process suggests their products were obtained illegally and, when finally trying to activate the product with Microsoft, Microsoft said they don't "recognize this as a legitimate product." I made multiple requests to Mkskeys and, after delays, none of the procedures they provided worked. NONE. Go. Flee. Run away. Don't buy ANYTHING from Mskeys

Spent money for nothing, do not buy!!!

Though the installation process for my Microsoft Office was cumbersome the technical support team was helpful.

Despite having the key I was unable to download the Windows 10 software to my computer. The purchase of the key ended up being a complete waste of money for me.

I bought a Microsoft Office professional 2021 key and it did not work still waiting on them to contact me

Purchase was quick. First lic number was bad but they quickly replaced it. Good service.

I got it and followed directions and worked just fine

Quick response.
Key worked (is working at the moment, at any rate).
I would have liked a download link, but I figured it out.

I ordered the product key for Microsoft Office Pro 2019 from mkskeys.com. Then I downloaded the software from Microsoft and installed it.
It is telling me that I can't activated it due to the product code already being 'in use'
So, what can I do now?
Thanks in advance.
I sent two e-mails detailing the experience from my regular e-mail address - please see.
