Same experience here -- I bought a bunch roughly 6 years ago, some 
(most?) at Costco. I've experienced only one failure so far, in a lamp 
that gets used most often, turned on and off at least a couple of times 
a day.  Don't recall brand, but nothing I bought then would be available 
today, nor would brand performance correlate from then to now. :)

BTW -- LEDs run on low voltage DC, so be on the alert for noisy DC power 
supplies.
