Aodee PIR Motion Activated Wireless Door Bell (32-Melody Choice)

Pros: 1. Very good value for money 2. Good chimes with 9 songs 3. Melodious sound, I think its polyphonic or MP3 4. Can select the sound volume, louder or softer 5. The sensor unit provides hole for external power source such as DC Adaptor

Cons: 1. Need plenty of batteries: 3 AAA batteries on sensor unit, 3 AA batteries on Melody/Bell unit 2. Units color are white. Since I want to camuflage the sensor unit, I wrap the unit body (not the 'eye') with black sticker.

Other: Cheap and usefull

Pros: - Very useful. - Adequate construction quality. - Price could be lower, but it is not so bad. - Works as advertised.

Cons: None so far. I ordered it to replace a broken unit (after two years of uninterrupted use) and it is performing as well as the replaced unit.

Other: Buy it now. It is a good product for an adequate price.

Pros: Units color are white in color and you Can select the sound volume, louder or softer. The sensor unit provides socket for connecting the external power source. Range is Good

Cons: Need lot of batteries: you need 6 batteries for the unit to function.Since everybody wants to camuflage the sensor unit which gives blinking red light you have to wrap the light with black Tape.

Other: the 'eye' cover is made of elastic plastic rather than hard plastic which may reduce the life of the product

Pros: the selection of chimes is quite impressive, the range of the unit is very nice (about 30 feet in my case), has continued to work for over a year so far just need to keep fresh batteries in it.

Cons: the motion sensor is hard to turn on and it can take several tries before the sensor will work, you can only cycle thru the chimes in one direction so if you pass the chime you are looking for you need to go thru all 32 again to get back to it, very limited English instructions.

Other: bottom line, I am very happy with this purchase and I am considering buying another one just to use for more pranks at work.
