In our experience they are good and realiable with a quick response.
Once you have an account with them you even have a personal relationship manager you can call/mail/skype to.
They have a bigger risk appetite even for Crypto but they are not cheap at all so they targeting high risk business.
Using them personal since 2019 - they delivered on all there promises - no matter if the MasterCard they issue on there own or the Mobile App / SEPA Instant - every promise was realized in the time they mentioned.
That's why I keep the account even without much usage and higher fees because I think once I need them they will be there.
