They used to require some affiliation to the armed services. My dad was an Air Force member and my wife was a member of TFCU before we got married. I think the rules to join are fairly relaxed.
When they started that Click Checking program it was 4% but it dropped after a while. I really don't pay attention to the rate and there are some other things I forgot. Direct deposits and electronic statements.
Just check out

All the requirements were things I did already, so it was a no effort deal for us.
