I think it's just when I'm searching for something where I don't know a good brand of what I want or I am trying to find a cheaper option but still have an acceptable level of quality.
Like those battery car booster things. There's a ton of 6-7 random letter brand, but some of them are actually ok, fortunately Project Farm tested a bunch for me

. So I kind of agree when just looking for certain things without a specific brand it can be a wave of garbage.
So I usually just know what brand I want before going onto Amazon and am more just price checking.
