That quote made me laugh hard.
To everyone around me, I keep advocating a simple principle: never use e-commerce sites for product discovery and evaluation.
Reviews are thoroughly gamed, and have been for many years now. That applies both to vendor-owned stores, where you can assume they're all heavily moderated or fake by default, as well as marketplaces like E-bay, where bribing customers to remove negative reviews or give better ratings is a standard business practice for sellers.
Product descriptions - those are always purposefully misleading. Hyping up the positives, hiding negatives, avoiding to provide useful metrics, and doing everything possible to prevent you from comparing between alternatives.
The best way I've found so far is to look for communities of people using a given product category, and read up opinions. Not review sites - these are, with few exceptions, just ads in sheep's clothing. But smaller, purpose-oriented communities are much harder to game thoroughly. So personally, unless the product category I'm exploring has a recent review on WireCutter (in which case I just buy one of their top picks; never been burned this way), the first thing I do is googling "<product category> site:reddit.com" and do my research there.
