kidde combo/smoke-carbon monoxide Detector

product was incorrect item. I ordered Kidde HARDWIRED Combo Smoke/Carbon Monoxide. I received combo but NOT Hardwired. Upset because I hired a handyman to install. Cost was $50, only to have him tell me it was wrong item!

Verified Purchase

I rated the product this way because of the ability to get the product from different places. Seeing that the Walmart brand is known and dependable I would believe that the product pricing would be a little better for this item. After shopping around the price difference was only a dollar or so. It really comes down to preference but since I have been a Walmart customer for 20 years they will ultimately win out.

Useless Garbage

As many others have said, multiple 900-CUAR units in my new build failed. 3 beeps with no alarm condition but the LED is off. New batteries, unplugging and plugging back into AC, etc. I'm not going to keep buying these so will now have to uninstall all of them and get covers for the holes. Complete garbage
