The problem with reviews from individuals (trusted friends or complete strangers), is that for major purposes they only get to deeply evaluate a single product. So they could tell you if they are happy with the fridge they bought, but they wouldn’t be able to do a detailed comparison between multiple fridges.

This will lead to you getting a product that’s good enough, but there may be a superior quality/value option that you don’t know about

Yeah, but it might be a satisficing approach. Most of us don't really need to optimize an appliance purchase, just not get screwed.
