I used to read CR faithfully until I noticed a few things. First back in the late 1990's they slammed by Miele DW because it had a filter that had to be rinsed, saying that you would use just as much water to rinse the filter as the water the DW saved. This was very different than my experience so I began to wonder if they actually had data to back up their statement.
Next problem came along when I tried to fill out the reliability data survey. They would not accept ratings on machines older than 6 years. So there I was with my DW at year 9 with no problems but unable to add it to the ratings review.
Finally I noticed that they began sharing very little information about their testing methods instead the just posted the ratings and short paragraphs stating their recommendations...nothing about how they tested to come up with their recommendations.
At this point I decided that I might use them as a starting point if I was going to buy a new appliance, or I might NOT.
Seems like for appliances you can get better information right here on this site. Cars and electronics might be another thing, but this site has a lot of real world appliance experience being shared.
