It drives me CRAZY!
How often I want to know something about a product (something less popular than smartphones, let's say IP cameras) and I find only ~3 reviews, I watch them all and they are all full of BS, because the reviewer has no experience with the product type they are given, they just follow the manual/or some given instructions by the sponsor how to make the product work. So I still know nothing about the product, its pros and cons and I can spot mistakes and BS even in those basic info that was given. In this specific case of IP cameras for example there are TONS of videos NOT showing the real video feed (recordings) from the camera, they just record the smartphone screen with another smartphone/camera and that's it.
