I'm very happy with my Samsung washer and dryer units (now 1 year old), thanks to input from CR reviews, lol.
From automotive standpoint, I never use CR for anything but it's reliability data charts and they are quite useful (and correlate reasonably well with long term ownership experiences).
Yes, it's hard to beat CR's reliability data. J.D. Power tries to (and has more different categories than CR), but doesn't seem to have as much consistency in their findings. Like you, I have found CR's reliability data to closely approximate my own experience over the years....with one exception. My 2006 Outback, though not bad, had some fairly early failures (power window-regulators, engine-coolng fans), which were not typical of most Outbacks. Fortunately, though, I avoided the earlier head-gasket issues that engine was known for.
I didn't know Samsung did washers/dryers.....I thought they were mostly into electronics and telecommunications. I've always had good luck, though, with Maytags and Hotpoint (a GE division).
Do you get the yearly CR reliability questionnaire/survey?
