I have a set of Novara (REI) panniers I bought over 15 years ago. Fronts and rears. I don't know what model they are. I have used the rears pretty consistantly over the years for commuting and groceries, and the fronts moderately. Except for some fading of the colors from the sun, they are in perfect shape, not even a fray. I see these panniers come up on ebay sometimes and I'd get another set if I needed to. They last forever.
I have a full set of Jandd panniers. I've only had them 5 years or so and do one tour a year with them. I occasionally use them around town. They still look new.
