I don’t pay for it, but I have premium for a year. There was a promo in which you got premium for a year if you got 3 other people to open a Revolut account. Honestly, I don’t notice a single difference from free. I already had turbo transfers since I used the premium trial last year, for some reason I kept getting the turbo transfers after downgrading.
The card, setting aside the design feels more flimsy and cheap than the standard Visa one, something other people have complained on the Revolut forum.
I’d say the worthwhile thing you get with premium is the insurance package, tough its overpriced for what it is. 4.99€/£ would still not be terribly cheap but would be more fair and hopefully they could at least remove the ATM limit
