Rated 3.1 out of 5 by 9 reviewers.
Rated 1 out of 5 by False Chirps To Keep You Awake These detectors emit a random ( sic. random not every minute) intermittent chirping day and night. Similar to the old low battery chirp BUT RANDOM. A low battery alert continues once a minute - until you replace the battery and the termial voltage of the battery is above the reference voltage. There are random single chirp tones from 2 of the 4 SA 710 units I bought. The single chirp may not reoccur for a day or more. I am replacing a roof and the inspector requires smoke detectors throughout the home so I purchased 4 of the SA 710 and one CO2 detector. So 50% of the SA710 detectors ( 2 each ) chirp randomly- under any condition, in any room, hot or cold, fans on or off, new batteries any voltage.... If you get these, allocate some of your lifetime allocaion time to waste locating the culprit, measuring new battery voltages, swapping batteries- fiddling to determine the problem, putting the worst offenders away from the bedrooms so you can sleep at night. Reviewers say " Oh get the photo detector units they are more sensitive". Baloney, I never had problems with ionization detectors ( I just moved ) and having owned 5 homes- with ionization detectors in each one. They always worked reliably,cheap. I suggest do not buy these. What is worse than an intermittent safety device? Nothing ! These are more than twice the price of cheapo ionization detectors. I would suggest that you go get the Kidde Battery Operated Smoke Alarm Model # 21008051 Store SKU # 182262 for less than $5 from home depot and skip these malfunctioning SA710 units.

Rated 1 out of 5 by Struggle with the battery Very difficult to remove the battery from the unit, when it is time to replace it. What a terrible design. There is no engineering at all. December 18, 2013
Rated 5 out of 5 by Great product The suburb I live in requires these in every home. Home Depot online had the cheapest price; even cheaper than in-store. I needed 7, they were in stock. I installed them without issue, quickly in fact. I like that they come with a battery and installation hardware. Reliable--haven't had any false alarms. October 28, 2011
