Project Farm is poorly controlled, sample-size-one, poorly-designed-but-very-specific "testing." It's entertainment, not actual useful product testing, and a good example of this would be his "let's see how many bolts this impact gun can remove in X amount of time" - each time a bolt is screwed on and screwed off, it polishes the threads, changing the amount of resistance.

It's of slightly better quality than the usual youtube comparisons.

Channels like his are wildly popular because corporations prefer inexpert entertainers aka "influencers" and "creators" over product/market experts, so they shower the popular ones with free shit to "review."

This is one reason you see e-bike companies heavily courting the tech press; the tech press know fuck-all about what to look for in a bicycle, so for example, they don't notice that the bike has Chinesium bearings that won't survive being ridden in the rain, terrible no-name tires with little flat protection and high rolling resistance, and brakes made of chewing gum that perform much worse than proper offerings from major brands.
