5 out of 5 eggsGreat!

Pros: I didnt buy this product from Newegg, but we have two of them.
-They are inter-linkable which means they all link up together wirelessly
-When one smoke alarm detects smoke, it will send a signal to the other smoke alarms letting you know that one smoking alarm is going off
-When the battery starts to die, it will make a constant "chirp" sound every 5 minutes reminding you to replace the battery

Cons: Nothing!

Other Thoughts: A great buy, and will be buying another one!
