Absolutely agree. SD promotes a lot of junk on this platform. Amazon currently was ordered to make sure the junk it sells meet certain standards. SD promotes just about anything cheap and a lot of it are junks from the world's factory so that it can make money off it.

I have their interconnected model. If CO is detected somewhere, all units go off. I have not had occasion to test it so I can't say anything about quality/accuracy.

I have a few of their smoke detectors and carbon monoxide detectors that connect to a hub. The setup was super easy, battery life has been great so far, and range is very good. Build quality is also pretty good.

be advised... the sensor is 10yr but the CR123A Battery is 5yr
so you'll need another ~$10 Battery before the sensor expires.

My battery powered smoke detector eat two batteries in six months. So 40 batteries in 10 years. What's the issue here?

My smoke detector that's connected to the grid has batteries that run out in a year... That's 20 batteries (it takes 2 AAA) in 10 years and I have to pay for electricity for it.

Same.

But realize this deal is for the stand alone model (not interconnected).

We get it…ChengC5391. He never said everything Chinese was shill or junk. But we all know it's far too common for shill wish.com, temu, alibaba nonsense to make it onto SD. It's a valid question with a simple answer—no need to get offended.

SD is owned by Goldman Sachs. Their job is to make money.

I have seen the Kidde ones similar to this design regularly on sale at Home depot for $15. Last time they were that price I bought several to put all around the house. And they use regular AA batteries.
