The Google Nest Hub Max takes everything that was great about the Home Hub and makes it a little bigger. That means it's still a great product but only you can really say whether you need to spend the extra £80 on an extra three inches of screen real estate, slightly beefier sound and a camera.
Brilliant usage of the screen; Google Assistant is as smart as they come; Excellent mics
Optional Nest Aware subscription is pricey; Camera feels a little creepy
