I don't understand why so many people and companies feel the need to just spam reviews, SEO and questionable ads. It's like almost no one has the idea that may we start with a good product, then we'll tell people about it. It's always a question of what you can have produced cheaply in China and how do we then trick people into buying it.
As it stand you can pretty much assume that if it's advertised, or is promoted on social media, it's going to be a shit product.
To some extend I'd exclude certain types of YouTube reviews, because they frequently aren't paid by the manufacturer and making a video with real people and real data is to expensive to waste on scams.
