I've only ever used bank of irelands online banking. I've had a lot of issues with logging in since they changed the pin entry to a drop down menu. I was locked out three times, despite entering the correct code on all nine occasions. How does it compare to the rest? I find that I can transfer money from my current account to credit card account on a monday and it might not enter my credit card until thursday or friday, which has caused me a bit of embarrassment in the past.
I find permanent tsb open24 service very good. they also provide a good phone service very little waiting around (press 1 for loans,2 for credit cards...etc...)
