Breville Eye Q toaster review: a ‘revolutionary device’ that makes perfect toast without me trying

TL;DR

  • Traditional toasters rely on time, which is an imprecise measure for achieving perfect toast.
  • The Breville Eye Q toaster uses a heat-resistant optical sensor to monitor the browning of bread in real-time.
  • This technology allows the toaster to adapt to different bread types, thicknesses, and temperatures (including frozen) without manual adjustment.
  • The toaster offers seven shades of browning and a "a bit more" function for customization.
  • A dedicated bagel setting toasts the cut side more effectively.
  • The toaster is easy to clean and its exterior is resistant to tarnishing.
  • Despite impressive performance, the precise browning gradations between settings were not perfectly consistent during testing.
