Nice alarm > Problem mounting plate
Super easy to connect; super annoying to mount. Most alarms either have a hinge and just "click" to the plate or easily twist into a position to flush nicely. My old battery-based alarms mounted/unmounted easily - no issues - none, this thing - what a mess. Out of the package, the method used (a twist on) never crossed my mind for concern; however, the tolerance to twist on is so narrow that it does not easily twist on. I have TWO of these and neither one wants to twist into position. Now I have to find some alternate way of flush mounting this to my ceiling.

    I am surprised by not being able to determine the manufactured date. Since this item has a set life of seven years. So I purchased several that I purchased in 2020 that had been made in 2016.

    Easy install until you activate then if you don't have the instructions in your hand it's frustrating. Additionally really small print. I finally when on line to find out how to turn off the alarm. Even though it's hardwired it will not interact with my other alarms (which are all Kidde). Also different baseplate from Kidde and a little flimsy so watch tightening screws as it will not mate correct if there is slight warping of the baseplate.

    I have had to replace too many smoke detectors before their time. While I can return them its always a hassle to deal with it as I have t call them to make it happen.I would try a different brand but i have about 13 that I would have to replace at once. Instead I just live with it.

    warning.....check the manufacture date of the alarm before purchase (on the back of the unit inside packaging)
    We recently purchased 2 of these alarms due to ours going off with warning beeps. After doing some research we learned these alarms are only good for 7 years, and they have a “limited warranty” of 5 years on the packaging. When after 1 month our alarm started to give warning beeps we took it down and discovered the manufacture date of the alarm was 2011. These were purchased less than 2 months ago. There is no manufacture date on the exterior of the package you have to open the box and look on the back of the actual unit. At almost 30$ each why is home depot recieving units manufactured in 2011. 8 year old unit which have an expected life of 7 years?

      Both defective within a month
      I bought two to put in a house i was renovating. The wiring was correct. Tested and checked. Both units had power amd new batteries. Both started chirping within a month. Re checked everything, replaced batteries, they did it again. I spent $108 on two detectors that dont work. I would not buy these again.

        It looks/feels like the big brands, so I'm inclined to trust the hardware, but this brand apparently forgoes a marketing budget to pack four sensors into the unit, and for a good price. With house explosions (like recently in Andover, MA), I'm surprised natural gas sensors aren't mandatory already... Probably someday. I do like the always-on green LED too, compared to the red LED in the competitor product I'm replacing... Small difference, but green feels like "all OK" and red always felt like something was wrong, to my subconscious at least. I'm hopeful that the dual smoke/fire sensors will truly suppress false alarms. (That wasn't necessarily a problem with my old sensor, but still it's nice to have both, for peace of mind, and to hopefully avoid false alarms too.) This unit supports the extra wire to trigger any other detectors that are wired to the same circuit. That might be handy in some situations, but when my old units began to age-out and fail, the constant beeping (from all three alarms in my particular setup) was very annoying, and for some reason it was very difficult to figure out which unit was the culprit. So when installing these new detectors, I left that wire disconnected, so each will operate solo. They're each loud enough for my needs, and the networking is optional... Just FYI. The wiring harness was easy enough to install, but I do wish all manufacturers would adopt a standard. Light bulbs are interchangeable, so why can't smoke detectors play nice too?! Same for the mounting bracket... They're all basically the same, but slightly different geometry so you must install the new bracket and send the old to a landfill... after just 7-10 years. Unfortunate and unnecessary. In general, I'm happy with my new detectors, and would recommend them for the price/value.
