They are legit. People on Reddit love the site and regularly recommend it for subscription based software. In fact, for my fireTV, I purchased an AdGuard Lifetime mobile key there.I contacted this company for some more information. Specifically how long I could hang onto the license key before I had to use it. I still have over a month left on my license. I did not get a reply back at all. And I did check my spam folder. I am even more leery now and will not be buying from them. If they ignore me then I won't buy from them.
Don't represent Adguard, but purchased my subscription there a year or so ago....They periodically have sales.....I did. I was just very apprehensive about buying from a company that wouldn't respond to a support request. They still haven't responded yet. Anyway I used a credit card that I knew I could dispute the charge with if the company turned out to be a scam. But I was given a license key within seconds and all is well. I now have 2 PC's and 2 mobile phones with lifetime Adguard. Now I need to figure out why I can not use my mobile data when Adguard is turned on. No data will flow. If I turn Adguard off on the phone then I have data flowing again. I'll try and figure this one out. Always something.
