Wired Cuckoo Bird Tone 80dB Doorbell (AC 110~240)

Pros: It works great and makes a beautiful sound, so far without any problems just keeps on tweeting... also a relaxing sound, so you dont get annoyed when someone is at the door

Cons: didnt find any yet.. maybe just the one (but applies only to some people) it didnt fit my original setup of old door bell, but with a little electric knowledge can be done on your own (dont forget to shut down electricity in the house before you start messing with wires.)

Other: i think its worth a buy if you are looking to get a door bell.. also i saw nice wireless doorbells on the site.. but it will be eating batteries.

Pros: Easy to install, no need to be an electrician, low price, and the material good enough, the buzzer sound is not very loud, and not stressful as other bells. Good choice if you want a sound that does not leave you nervous :-)

Cons: I have dogs and cats, they are very curious when the doorbell rings, their behavior is very funny :-) The sound of the bell is not perfectly like a bird, but it seems enough. The doorbell rings just as the person is pressing the button it

Other: It's a good bell for those who usually gets nervous about annoying noises
