> Reviewers that try and apples to apples all products by comparing cost, size, advertised features and ergonomics are doing no better than you or I opening up a package and appraising it.

Unless you're buying every product on the market and load testing them in your garage, some folks do a lot better than that (e.g. project farm, or torque test channel).

But it clearly requires time and passion, and serious rigs for some of the tests (not everybody has a Skidmore lying around).
