First Alert Slim Photoelectric Smoke Alarm with 10-Year Sealed Battery, PR710, White

Work perfect

works well

I'm disappointed in this model of smoke detector. My brother is a firefighter and insisted I get a smoke detector for every floor of my home, and said that if I bought one with a sealed battery I would be able to set it and forget it for about 10 years. I begrudgingly spent money that had been gifted to me on these for safety rather than something fun, and I at least felt secure. Until the upstairs unit started firing off at nighttime. This must have happened 5 or 6 times, jolting me from sleep in a panic, before I disabled the unit. My brother said I should use canned air to spray through it in case something was setting it off but that didn't help. Now, less than a year after the purchase of these 3 units, I've got my basement one giving a low battery chirp every 30 seconds or so. This was supposed to last for *years*. So far the only one that hasn't shown some sign of being defective is on the ground floor, so I didn't bottom out all my star ratings but 2 out of 3 is a pretty horrible rate of defects.Update 10 June 2020: I was just woken at 6:15am to the upstairs alarm misfiring just like the first faulty one did. It looks like I'll have to replace this one too. The good news is these units are loud as hell. The bad news is whatever they don't like about my home seems to be a common issue and not a simple bug with only one of the three I originally bought. It's really disconcerting to wake up and rush through your house looking for the source of a fire you expect to end life as you know it only to realize it's just another defective smoke detector. Dropping my review to one star. 3 out of 3 units malfunctioning is a real drag, especially given that the product description brags of how its unique design cuts down on false alarms. I've filled the house with smoke cooking and the device never made a peep, but we get all 85 decibels at random while trying to sleep.

Had to purchase smoke detectors with 10 year battery due to new housing regulations. They appear to function fine. Had no difficulty installing. Was able to save a little money by buying in bulk.

I picked up the First Alert Slim Smoke Alarm (PR710) because I wanted something that looked clean on the ceiling and didn’t require constant battery changes. The slim design is definitely a win—it’s way less bulky than the old alarms I had. Installation was super easy too. I just twisted it into the bracket and that was it. The 10-year sealed battery is a huge plus since I don’t have to worry about swapping out batteries every year. And knowing it uses a photoelectric sensor for smoldering fires gave me some peace of mind.That said, I’ve had a couple of false alarms go off in the middle of the night, which was pretty frustrating. Also, a friend of mine who bought the same model said theirs started beeping low battery after just a few years, even though it’s supposed to last a decade. One other small gripe—if you’re replacing an older First Alert alarm, the mounting plate might not match, so be ready to adjust. Overall, I like the look and simplicity of this alarm, but I’m keeping an eye on its long-term reliability.

My previous First Alert lasted almost exactly 10 years, and I expect this one will too. It was easy to install, and it’s nice to know we can set and forget it!

Thankyou Amazon exactly what I ordered.

Easy install each room needs a smoke and carbon monoxide detector they saves lives
