Kidde Worry-Free Smoke Alarm, 2 pk.

I purchased this 2 pack in January. Last week, one of the units malfunctioned. It went into full alarm for no reason and I couldn't get it to shut off. I had to destroy it to get it to turn off. I called the company and they are sending me a replacement.

As a landlord with many apartments, I am constantly buying smoke alarms and a lot of them. This two pack is a great value and I love the 10 year battery. Now I don't have the maintenance nightmare of changing a couple hundred batteries each year. The cost of the batteries alone pay for the cost of this new one over time. Also, it reduces waste to the ecosystem.

Easy to install-battery life unknown but said it should last 10 years

The media could not be loaded.  Have a number of these bought on Amazon in 2022 (2 years ago). Sometimes they give false alarms. Normally easy to solve by depressing button on smoke detector face. I had one however that ran a false alarm in the middle of the night and would not turn off. Short of whacking it with a hammer, thus destroying it, I wrapped it in a bath towel and stuck it in my freezer to minimize the smoke alarm alert until I could resolve it next day. About 12 hours later, the smoke detector was still triggering an audible alert. Note, my freezer is set at -5 Degrees Below Zero (that's -20.56 degrees Celsius)(photo). Contacted company. On hold and after 30 min wait, company sending replacement in 7-10 days. Company stated to turn permanently off there is a switch on newer models.

Nice to have
