We have had a GREAT experience with PenFed! Joined about a year ago to get the Visa Platinum Cash Reward card for the 5% cash back on gas and no FT fee. It's been great so far! 5% back statement credit every month on our bill. (No hoops)
Customer service has been great. We recently refied a car loan. Filled out the online app, went down to the CU, signed a couple of papers and POW! Walked out with a check for $25,000 to pay off the other bank. Not too bad for a savings account with $10 in it and a credit card open less than year.
We are looking to refi our house loan with them and also another car. Nothing but good things to say about PenFed so far. I for one, would recommend Pentagon Federal Credit.
