HAPPY WITH MY PURCHASE !!
I WAS IN NEED OF PURCHASING A REPLACEMENT SMOKE/CARBON MONOXIDE ALARM. THERE WERE MANY TO CHOOSE FROM, MOST OF WHICH WERE QUITE EXPENSIVE. I SETTLED ON THIS UNIT BECAUSE IT WAS HALF THE PRICE OF THE OTHERS SHOWN. I RECEIVED IT VERY QUICKLY. I HAD NO PROBLEM SETTING IT UP AND INSTALLING IT. I'M VERY HAPPY WITH THIS PRODUCT, SO MUCH SO THAT A COUPLE OF DAYS LATER I PURCHASED ANOTHER ONE TO REPLACE A SECOND ALARM THAT STOPPED WORKING. I ALSO LIKE THE FACT THAT THE WARNING ALARM SOUND IS CLEAR AND AUDIBLE AND THAT THE UNITS WILL LAST FOR 10 YEARS.

Buy it, install it and leave it alone for 10 years
Great smoke and Co detector and you won't find a better price anywhere. It also comes with 10 year energizer batteries.
