What sort of products?
Even within given products the needs and requirements vary massively -- I am not going to suggest the same drill to my uncle that wants one to use a few times a month to fiddle around the house and shed vs a client that wants to equip a fleet with ones that commonly go through 3 batteries a day vs a sole trader builder that might also do the 3 charges but just needs one for them.
I can similarly give an engineering perspective on a kitchen tool but if I (with forearms that come from using a drill all day) only use a hand drill style whisk to spin up eggs and milk once a month rather than everyday making thick batter whilst being someone's grandma it is going to be harder.
Amazon and youtube can yield interesting things but vary massively as well. Marketing departments have decades (if not the better part of a century -- the 1920s is when serious psychological and analytical things came into play in advertising) to perfect their pitches, pushes and whatnot. They will hire people to outright lie, and also give things to individuals they deem prominent enough which in turn makes it somewhat dubious (they are quite manipulative to such people -- see any number of stories there of advertising firms wanting it all) both in general (it is not impossible to be objective in such scenarios but it is hard) and down the line ("positive" reviews = more product* = more clicks/views = I still eat and have a roof over my head) and because even without that if said people also actually do stuff rather than just review you see the product in further things.
Standalone websites are also affected by things beyond that (they might have baseline advertising on a sidebar or something but that is another person to please) but still have many of the same issues.
*average product is what $50, say 30 for the year (and that is a low number) then that is $1500 just on products to look at per year. Bump that to 50 per year, maybe get a friend to do their own things (100 now) and of course $50 for a gadget is nothing even in consumer tier and that number only grows.
Print and once were print but obviously that is dead are not exactly untroubled (see the many woes of gamestop and ign) but also might be corporate owned (

If you can learn to spot jokers (amazon is full of them), spot shills, personally I suggest ignoring those with awful writing and grammar, negate/lessen things mentioned, learn some of the field you care about (including the physics that underpins it), maybe find some cynical bastards (80% of the time these will be older people that have been around the block once or twice, though the 20% of younger cynical bastards are not to be overlooked) that know what they are doing, devise your own tests and things to look for, maybe see if you can get some hands on time with things (narrow it down online, then wander out into the real world to see the final deal).
