but is that true? you're standing in target, looking at air fryers. they're all priced differently. how do you know which is the good one? is it really the more expensive one? highly doubt it. and it's the same almost with everything now. price carries a very low signal.
Honestly, I'd probably look at Wirecutter and Cooks Illustrated, both of which I have subscriptions to. I'm not going to trust them on every product I might buy but for something like air fryers they're probably not going to steer me too far wrong.
