"The licenses I've purchased over a few years have all worked fine (still to try 2 of them). That said, be advised your credit card is not secure with them. A virtual card number I used with them (only good at their business; only they knew it) appeared on the dark web several months after I placed an order with them. There would be no other way for this number to get leaked other than from their business. I learned of this leak because my credit card company notified me that this virtual number was being used other places (fraud alert) and of course declined. I would strongly suggest you only use a virtual card and not a hard card with them. Much easier to fix if leaked."

"Easy to download....Great!"

"I bought keys to Win10. They were very inexpensive, but they worked fine. I have no complaints w/ this company. One point to be aware of is that they show up on the credit card statement as a different name, which has changed over the few years I've been using them. Knowing this in advance may help prevent you charging back a valid charge."

"Service inbox is full and I have no way to contact them to let them know they never sent out the keys. Not in my spam folder either.

Update: I did have someone reach out to me after review posted. I guess that's how you get in contact with them.
Added two stars.
