I have 12 of these in my house of various vintages, the oldest of which was manufactured in 2017. Oddly enough, the 2017 model has been the most reliable. Several of the other 7010B's have generated false alarms, often in the middle of the night. All of my units are linked together, so if one is triggered they all sound the alarm. This is a great feature to ensure nobody sleeps through an alarm, but when it's constantly false positives you start to get a little agitated. Mine went off again last night around midnight, and by the time I figured out which unit triggered the (false) alarm, I was so angry I chucked it off the ladder. Obviously, I'm heavily invested in this platform and it will cost me a grand to replace them all, so here I am buying another probably defective First Alert combo alarm while whining into the void about how terrible they perform. So it goes.

Bought in May and in September it starts randomly beeping for no reason. Malfunctioned!I've always used this unit in the past and will probably give it one more try.

I bought this detector to replace the battery detector in order to sell my house (hard wired detectors are now required in Oregon to sell your house). However it didn’t come with the screws or wire connectors. Otherwise it’s an ok smoke/carbon monoxide detector.

I use this model of the carbon monoxide/smoke detectors in areas that I would normally get false alarms. This particular unit doesn’t seem to put out as many false alarms so it works a lot better !!

This seems fine although it came with a piece of tape that read "false alarms". I haven't had any yet but I do think these are overpriced and should have an internal battery since their main power is electricity. Replacing 9 of these after 10 years is also a costly undertaking.

Had to replace all the detectors in my home and these have been great so far! Had no issues with install and they all came packaged wonderfully. Some of the detectors I've received from big box stores haven't worked or been defective. All of these worked right out of the box. Didn't have any issues with activation and they work great when I test them each month. Great product overall.

I have 12 units interconnected across the house. One unit went off and that triggered every other connected detector. There was no smoke or fire. I clean the units periodically with compressed air. After the first false alarm I cleaned all detectors. 10 days later the alarm went off again and this time a different unit triggered it. I’m looking for an alternative as these units are expensive but unreliable.
