Love Revolut. I was an early adopter using it primarily as a fee free travel card. Over the past few years (probably since Covid) I’ve also been using it as my everyday payment card in the UK (where previously I would have carried cash) and I use the “save the pennies” feature at x10 to create a useful little savings account for treats.
Never had a security issue but I do concede that the protection is probably lacking. I don’t keep too much money on it for that reason.
I’m sure that the likes of Revolut have forced the mainstream banks to modernise and up their game so welcome their entry into the market personally.
