I really wanted to get a Windows 10 Professional key to activate my new custom gaming system and was really skeptical as this was my second attempt to buy a key online. In the past I had always purchased either a retail or OEM version with physical media (usually a CD or DVD). Now everything's online, including the ability to create your own media/usb stick for Windows, it was easy to setup and install. at no extra cost. I couldn't just upgrade using a previous windows key because they were all Home or Standard versions, and I wanted the Pro version this time around. The other place I had already tried (kinguin) wanted around 89 bucks, which in all fairness, I was ready to pay. However, they kept denying my Visa card. Frustrated, I decided to try Keysoff as it was also recommended by an article I read on TomsHardware.com where they also mentioned kingquin as being a reputable place to get legitimate keys. Perhaps kinguin was just having difficulties with their merchant software, I don't know, but at any rate they kept telling me there was an issue with my card (when I knew there wasn't). I confirmed this when my purchase at Keysoff went through IMMEDIATELY with NO ISSUES and within minutes, I had my product key sent via email. In windows 10 Pro I went to the Activation Settings page, clicked on Update Product Key, and entered the code with my fingers crossed.... Bada bing....bada boom! I JUST WORKED...After letting out a sigh of relief, I put that issue behind me. However, I thought it worthy of a review due to all the scamming out there, I just needed a place that worked that I can trust. So far, Keysoff.com has my 1st vote. Only time will tell what the future holds, but at this point I'm VERY Satisfied with them.
Gave the money at a good discount. Received the code worked no issues.
Key arrivata immediatamente e completamente funzionante
Thank you very much for the fast solution, very good thank you :)

I was skeptical at first but for as little as it cost plus I had a coupon code it was definitely worth a shot. Once I placed my order I received a confirmation email and about a minute later I had my product key and it actually worked.

I contacted after sales service, and they answered with a new valid key really fast !
I recommend it !
