Excellent! 
Quick and easy Banking. 
Easy account set up. Set up my account on my phone, in less than 10 mins I had a new bank account. All the functions you'd expect, plus new ones I'm still exploring on the app. Had my Debit card in 8 days, had my BIC and IBAN within the 1st hour, was able to change all my direct debits once I had this. I'm still amazed how quick transactions are, I always know how much is in my account, No waiting days for Irish banks to update transactions, I get notifications as I walk out of shops for purchases I've just made. I recently paid a bill online and got a notification form N26 before the companies website confirmation page came up, its that quick. Customer service is very German quick and efficient, can't complain about that.
I'm still finding new stuff to try but so far I'm delighted with them.
