I’ve generally had good experiences with Privacy.com. It seems like a decent solution when I want something from a semi-reputable website.
I particularly enjoy the bit where cards are vendor-locked, which has been interesting to observe in a couple of instances where a site seems to have had their credit card db breached and the attackers turn around and try to use the card on another site, where it is inevitably denied, but I still get an email that shows which site got hacked and where the attackers were trying to use the information.
