ALDI Wireless Doorbell $12.99

Adjustable to three operation modes 100m range for transmission Includes table stand and wall bracket and wall mount   Purchased this on Friday night, unpacked, installed batteries and had a play with it, not bad so put aside on the counter with a view to install next to front gates over the weekend. Some time during the early hours of the morning the thing went beserk making all sorts of noises that did not even remotely resemble any of the 16 melodies - OMG. Repack this "product of the week" back into the box and tape docket to the side for return and refund.   Checkout my final soultion for the front gates.
