Today's deal certainly pushes all the right buttons. Ding dong! We're offering you a wireless twin chime doorbell kit for just £14.99, saving you 55% off 1byone's price of £32.99 (correct as of 18.1.16). The sweet sound of a doorbell ding can signify great things (did someone say Domino's delivery?) or terrible things (trick-or-treaters on Halloween who want to steal all your chocolate). Either way, it's normally pretty important that you answer the door, and with today's wireless doorbell there'll be no more missing the postman, window cleaner or flower delivery from hubby (because obviously that happens all the time). This doorbell kit comes with one wireless doorbell, one plug-in chime, one battery chime and one bell. The twin chime kit is ideal for larger homes, or anyone who would prefer a chime output in two locations of the house, for example one upstairs and one downstairs. The waterproof push button bell is designed to withstand rain, wind and other elements of lovely British weather. With 100m coverage, adjustable chime volume, a flashing light to indicate low battery as well as someone ringing, plus 36 different melodies to choose from, make like Beyoncé and put a ring on it...
