Rated 5.0 out of 5.0 by bigbear A great purchase, no more need to replace batteries for ten year
It would be better if they like every other manager does use screw holes rather than those wacky slots that you practically need 3 hands to install the base. A number of holes in different location so that it can be properly aligned.

Rated 1.0 out of 5.0 by nondenom NOT A 10 YEAR BATTERY
Installed this "10 year life" lithium battery alarm in July of 2013. It is September, 2015 and the stupid alarm is going off every 15 minutes because of low battery. Took the alarm off the wall and took the battery out. Will replace with another brand. Ridiculous.

Rated 1.0 out of 5.0 by JimB 10 year battery?
So how come they only last 5 years? Perhaps it should be called a 5 year battery.

I agree with other reviewers on the battery life. Ours lasted 3 months before the 10-year battery died and the unit started chirping at 5am-- we had bought this unit just so this wouldn't happen for some years. We'll be looking for another more reliable brand, or going back to the replaceable battery models.

Rated 4.0 out of 5.0 by mikewisc Reliable alarm, but battery life is highly variable.
I have four of these installed, and one just gave me the beep alert that the batteries had died, This, after 3 years and 2 months. The others seem to be going along fine, testing okay and still rendering loud and clear alarm signals. So I conclude that the batteries in these alarms are a lot like light bulbs - they can last a long time, or go out prematurely - and you never know. It would probably be more honest if this product was billed as an an "UP TO 10 year alarm." Still, I don't mind replacing after over three years.

Rated 1.0 out of 5.0 by rickc 6 months... then it goes off anytime
Poor deal, if you take an extra long shower, turn on the shower heater, or look cross-eyed at it, it screams
