Pros & Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

This seems like a good product. It detects both smoke and co. We have these interconnected throughout the house. This is an exact match to my eight year old smoke andco2 that was installed in my house.

The instructions for diy are very good. It is both hardwired and equipped with a 10 year backup battery. Easy to install with an adapter if it is replacing a firex or kidde hardwired smoke alarm.

Cons

The pull tab to activate the alarm had been pulled staring the clock towards the expiration date of the life limited parts. They continue to beep, no matter what the directions say. We troubleshot all possible options, had them blown (cleaned) out and... Read More

The manufacturer's warranty covers them for 10 years for the original owner only - not me. When i opened my new 3-pack, i found a manufacture date of november 2020, they're already 13 months old. These were supposed to be brand new - instead they are ... Read More

Quality

Exact fit and upgrade from my old smoke alarms now smoke alarms and carbon monoxide detectors

Easy to install and the back plate is the same size as 11 years ago so no repainting is necessary

In all honesty i’ve only replaced 2 out of 15 so definitely not a quality issue

We built our house 10 years ago and these smoke detectors are wired all through the house

Price

Worth it since price is now 35 dollars

I’d recommend these i got them on sale

Purchased in 2016 for 18 dollars lasted about 8 years

10 year warrant but cost 6 dollars to ship replacement

Competitiveness

10 years ago i purchased and installed very similar units made by the same manufacturer a bit bigger and no carbon monoxide sensor

These replaced a different name brand that were up for over 10 years
