Consumer Reports https://www.consumerreports.org has been a pal to my wallet over the years.
Pros: Their surveys are free of Corporate influence in the evaluation of comparative product value. They offer in-depth studies and explain the reasoning behind their final conclusions/recommendations. Their large subscription following and Annual Survey results provide real world experiences from actual product owners.
Cons: The publishers are limited by their budget to addressing the most popular categories, so more esoteric products may never be evaluated.
