Not great but not bad.
The only security I've received so far is against my own transactions but when my card got used by someone else fraudulently on a Saturday (when the bank's closed), and my money was drained there was no security verification. However Great Basin did resolve my issue and credit my money back to my account first thing Monday when they reopened. Not being able to call ANYONE on the weekends, not even a 1-800 number is very frustrating. Most other banks can be reached out to even if the branches are closed on the weekends. I'll stay here for a while but I'll find another credit union in time.
