I bought a subscription a few months ago because I needed to buy several large appliances for my home, but all I found behind that paywall curtain was computer-generated tables of star ratings and statistics about mechanical reliability. Which is probably useful to somebody, but isn't something I found valuable.
I ended up ignoring CR's data tables, cancelling my subscription, and buying the same models of appliances my parents have because at least I could try those out in person and verify that they worked decently well without any glaring flaws.
