Bought to replace two 30+ year old smoke detectors in my in-laws home. Very easy to install. Done in 10 minutes. Work great!

Easy to install and at a good price. My old ones were over 10 years old. They stopped working. Replacing old one was super easy.

Product as described

Would Recommend

Customer service was absolutely the worst. When I called to confirm they had the product I was left on hold for at least 6 of their cycles finally gave up and drive to the store. I found the alarms with no help and did self checkout.

Would Not Recommend

I added this to the kitchen since the other unit was further away. it was a bit sensitive, went off while cooking bacon despite being 12 feet from vented oven. then despite being a year old, while out for a meal our cameras texted us loud noise. I returned home to a low battery alarm. Junk
