Rated 5 out of 5 by from Great product I bought this item because I liked the 2 in 1 feature. It was very easy to install.

Rated 5 out of 5 by from 7 yr lifespan, worth price mine just went out last week, after 7 years of faithful service, with no malfunctions along the way. Kiddie makes a great detector, and they have never let me down. This is a great buy, but they do have an even better model out now. This time around, I will be upgrading to the li-ion battery version with a 10 year lifespan ... that's three extra years of expected life, and no batteries to change, plus you get to keep all the same features. And at about $10-$15 more than the standard AAA version, the "higher" price really just buys all those AAA's that you won't need to install... saving you time, and putting less batteries in a landfill!!

Rated 4 out of 5 by from Decent product The alarm didn't detect anything as yet but I give it 4 stars because there's a design flaw when opening the battery door. there's 2 red spring loaded that sit upright when no batteries are in and it blocks the door from opening. Had to use a pen to push it down while trying to open the door.

Like the ability to replace batteries as the batteries don’t last thru winter any way. I always replace the batteries before each camping season. Works well as our old toaster worked to set off the alarm.

The only problem was some ignorant customer must have opened the package and stole the two batteries that were suppose to come with the item. I was able to scrounge up fifty cents to buy two batteries to keep my family from dying from C.O. or smoke.

These were chosen because of the ease of battery replacement and compatibility with previously installed and recently outdated smoke and CO detectors. A good price for good alarms.

New model has 10 year life span and requires 2 AA batteries instead of 3 for the old model, which is a welcome improvement.
