1 out of 5 eggsTerrible product

Pros: Good design

Cons: Bulky and use too many batteries for simple use.
Poor connection and short battery life

Other Thoughts: This product is a terrible product and make the company's name(Chamberlain) unreliable.
The connection between Intercom and doorbell lose frequently, so I have to reconnect the link a few times a week and the battery life of the doorbell is very short(one month) ridiculously. I don't think mine is defective but simply, the quality of product is bad. I would recommend Chamberlain to stop making this product, so they don't ruin their name.

5 out of 5 eggsFinally, a doorbell that works

Pros: So happy to finally have a doorbell that works. We've tried a series of wireless doorbell options and none worked consistently because of interference. This one works. I had a little trouble setting it up, initially but was able to add an additional receiver, so I can hear it anywhere in the house, without any problem

Cons: A little bit tricky to set up, but not bad.
