Mine has been excellent apart from the daily limit and merchants that don't accept their cards like cloud providers. Takes a bit of regular activity before support will raise the limit but the fact that Privacy.com cards show up as prepaid (try it out with the Stripe api, for example) is a show stopper for some narrow use cases - which overlap almost perfectly with spammers so who can blame the merchants.
It does become a problem depending on their POS vendor deciding to flag prepaids, I've seen several dislike this because of the ability to modify transactions afterward / tip or something of the sort, for the restaurant industry.
In case you need to in the future, i'd recommend privacy.com for merchant-locked cards.
