Customer review summary generated by AI, including incentivized reviews.Good basic CO detector
Purchased this to replace a fancier model, but have no complaints so far. Pros: cost and ease of use - just plug in and you're done. Battery backdrop does not chirp when you add new battery! (The dog says thank you for that.) Cons: doesn't have a digital readout and the access door for the battery was difficult to open. Had to resort to YouTube to figure out how to open but opened easily once I understood.
Very good service.
I bought this to replace an older carbon monoxide detector. The service was good and the employee was knowledgeable.
Great system
Great product for peace of mind. Easy to mount and use.

Chirps when it is time to replace unit
I previously had one and it chirped 5 times at the end of its 7 year life. I wanted to get the same brand as before. I like this one with the battery back up and electric plug in. I hope I never have a carbon monoxide exposure but if I do I trust this device will alert us.
Replacing a carbon monoxide alarm
This was a replacement for another alarm. It fit the spot, was easy to make usable, and has a good warranty. I had researched these alarms and this is one of the best offered.
Consistent
So far so good. This is the new model to replace a 10+ year old version of the same thing. I trust the brand at this point to protect the house.
Replacement footprint identical.
It’s a basic CO detector. Simple to install. Replaces the expired one precisely.
Very good product
This is my second one ,I was very pleased with the last one , it just run its course. I ove that its plug in with battery backup!
LEFT IN PARKING LOT my Loss
I purchased this product along with potting soil, but the problem was this.. I accidentally left the Carbon Monoxide Detector in the cart, in the bag along with my receipt, in the parking lot after putting the soil in my truck. My mind was on the loss of my brother and I was totally blank until getting home and realized I'd left it. I live 20 mins away and my wife called and gave description of the detector and explained what happened. The lady said she would go look and see if it was there but ...
Easy to install
Easy to install. You do need a small level to locate the two screws at the exact same height.
