I have had good experiences with Trastra after leaving Wirex.
5% spread, same Contis issuer, I see nothing special about them, plus the fact that all their social media TW,FB,Reddit have zero comments good or bad makes me wonder if they have more than a hundred clients.
If Contis is "not a problem", there are more known options for the card, probably with lower fees and spread too (like Binance).
At least Wirex move to MasterCard resulted more reliable cards, or better accepted by merchants.
