> Reviewers often have their issues really understanding how people use products, often because rapidly changing things to review, doesn’t allow them the time to truly use and understand a product.

The reviewer states:

    I’ve been using AirVisual Pros for the past five years.

so it's not like they're new to the field. They know what they want out of the product they're reviewing. That may not be what someone reading the review may be after, but that doesn't invalidate the review.

I'm not sure this contradicts GP's point - this reinforces that the author is comfortable using a different product (AirVisual Pro) and may therefore, almost paradoxically, struggle more with a product that displays data differently than someone who has never used either product.

To draw a parallel, I think an iPhone user may have a harder time using Android than someone who has never used either phone.

Admittedly, I'm another happy AirGradient user.

Yes, time to adjust and familiarize oneself with a new product is often too short. Let alone adopting new sensors into a smart home ecosystem and fully setting everything up the way you want, rather than just the default settings, etc.

I get a new laptop and phone and generally dislike it, because it's not what I am familiar with and it's not yet setup just the way I like it.

And then there is the fact, that the reviewers favoured product has a logo on the product page for the reviewers publication.

There is certainly potential for financial interests to impact reviews.
