I believe so, Costco and Lowe’s run periodic sales on them. Be sure to check the dates and don’t get the old ones. I like them because there’s no guessing if you heard 5 or 6 beeps. We had a traditional interconnected smoke/fire/CO alarm go off in the middle of the night and for the life of me couldn’t remember what the beeps meant. In my daze I didn’t want to get on the floor if CO was present but also didn’t want to run around if there was a fire. In my sudden awakening I wasn’t aware those thoughts were flawed. I grabbed the kid and bolted out the second floor window. I did a Google search on the beeping and found out it was my CO alarm. Anyways, I never want to be in that state of confusion where I don’t know what the proper life saving steps are. And you can have the alarm test itself.

That’s what we have, one in nearly every room. We use them as a whole house music system while cleaning, and intercom system when we don’t want to yell across the house, we can control the smart home devices, in a pinch we can use them to call anyone from our contacts. I like them, but seems most everyone did not.
