The Breville long-slot 4-slice Smart Toaster features an internal electronic chip that automatically lowers bread w/a single touch & regulates toasting time. Push-button controls include toast/cancel, a-bit-more, lift-and-look, bagel, & defrost. The A Bit More button automatically lowers the toast for additional toasting time if necessary. The Lift & Look button automatically raises the bread carriage during toasting without canceling or resetting the cycle. This enables you to view, & if necessary, cancel the browning cycle at any time.
