Review on Avantek WA-11 Wireless Door Bell - 1000Ft Range, 52 Melodies, 5 Volume Levels & CD Quality Sound by Kevin Fuentes

It is as loud as the existing mechanical chime (which gets very little use because its doorbell button is too far from the door). To install the doorbell button, I taped a magnetic sheet at the back and placed it on our front metal door. Very solid, not flimsy. No issues connecting with the chime despite the metal door, although there is a 1 second lag (but a LED light activates when the button is pressed, so it helps to assure that the doorbell is working). It looks good despite the plastic exterior, not high end, but not cheap. We will have to wait for the durability of the button and the batteries. For greater convenience, I placed the chime inside the existing mechanical chime box (it required to take the chime apart to make it fit in the box, using some tape, but I don't recommend doing so unless you know what you are doing - it is easy to break the internal wires and it will void the return warranty).
