The Nest Mini is the cheapest in Google's smart speaker range, making it a great entry-level product if you want to kick off converting your home into a smart one. See our full review of the Nest Mini, which received a full five stars.
Google's closest relative to the Lenovo Smart Clock would be the 7in Google Nest Hub smart display, which offers stronger specs and is closer to a tablet – but would (understandably) set you back £119. The 4in Smart Clock in comparison is smaller and essentially a Home Mini with a screen, in terms of functionality.
In our review of the Lenovo Smart Clock we recommended it as a justifiable alternative to buying the Home Mini because the price jump isn't too significant. Now however, Curry's bundle gets you the best of both worlds. At £49 for the bundle, you save on the entire cost of the Clock and get the latest Nest Mini too, making this offer particularly enticing.
