I agree, they're pretty awesome. My grandpa worked at Boeing, so my family started with BECU from way back when membership was only for Boeing employees and their families. I'm a third generation member! 
Some examples of awesomeness:
- They gave me a credit card with my requested limit ($750, I was clueless) back when I had ZERO credit score whatsoever and no job, just a $700/month fixed income.
- When my checking/savings accounts overdrafted due to automatic charges that were supposed to have been canceled, the agent I spoke with simply to understand what was going on volunteered to waive the fees, because I have such a long history of keeping my accounts in good standing.
- Last year they were running a referral program, giving both the referrer and referee $100 each for new accounts. My partner and I both made $100 from the bonus.
- Last year they aparently quietly replaced all members' cards, both debit and credit, with chip-activated cards, even if the card had still had years left on it before expiration. Very security-concious.
- They automatically lower the APR on my credit card on a regular basis. I've had it for 3 years and it's already down to 9.40%. Each time they do they send me a letter congratulating me.
Always a pleasant pick-me-up. - Zero fees for using BECU atms. And there's always one around.
- The Member Advantage program has some of the best interest rates I've seen, for the first $500. Currently I'm getting 4% interest on my checking and 6% interest on my savings.
Not trying to sound like a walking commercial, but I'm pretty happy with them. I wish CLIs were a soft pull, but I hear that's common with credit unions.
