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.
