This cordless wall plug in door bell comes sensibly and securely packaged.
It comes with a scredriver, to fit the alarm button, useful to prise the button open to fit the battery that comes with it. Washers and screws also supplied and a stick pad if you don't want to screw in.
Easy to fit battery and plug in. The plug has a four volume adjuster to the side and a button to change to any one of 36 different chimes.
This is ideal for the hard of hearing and elderly as the adjustable range is excellent, and allows my mom to hear this anywhere in the house or garden as she only has to plug into the nearest point to her.
Highly recommended and excellent value for money.
