🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.


The product under review functions as expected, with many users praising its reliability and easy installation. Some customers noted that the 9v battery included with the product was dead on arrival, but were generally satisfied with the detector's performance. One customer highlighted that the product's design is standard and not as upscale as previous models.

Pros

  • 👍 Easy to install
  • 👌 Works as intended
  • 😊 Great price
  • ✅ Reliable

Cons

  • 👎 9v battery is often dead on arrival
  • 🙁 Design is not as visually appealing compared to old models
  • 😕 Doesn't mention recyclability
  • 🙈 Short product lifespan

Should I Buy It?

Yes, considering its affordable price, easy installation, and overall functionality, it's a sensible purchase for home safety. However, you should also be prepared to invest in a 9v battery, as the included one is often dead on delivery and be aware that you may need to replace the detector after a few years due to its short lifespan.

  • Great detector
Size: 5.75 diameter x 1.8 depth
9v battery was dead when I received it, but I got it opened, so I can’t dock stars for that. Otherwise works just fine.

  • Nice, but I miss the KN-COPF-i
Size: 5.75 diameter x 1.8 depth
The media could not be loaded. This is a good Carbon Monoxide detector, but it doesn't look as nice as the obsolete KN-COPF-i that was flush mounted in the wall. After 7 years CO detectors expire and must be replaced. The obsolete model looked more upscale than the new model that is a standard Round design like everything else on the market. ... show more

  • Unit works well, but dead battery
Size: 5.75 diameter x 1.8 depth
It would have been so much better if the 9 volt battery wasn’t dead on arrival, I’d rather you say battery not included rather than sending me a dead one. Now , off to the store to buy one.

  • Required by law. Easy to install.
Size: 5.75 diameter x 1.8 depth
These carbon monoxide detectors don't have a long life. This is the 2nd one I have purchased in 8 years. They are very easy to install. I didn't really need the new set of wires which I hope can be recycled. I have no idea if the old detector is recyclable. There is no recycling info on the product or box. I have a detector because my condo is hardwired for it and it's required by law. It's my stove that produces the most carbon monoxide when the stove is turned on. My heat/A/C guy tested it. The detector is located by the gas dryer and furnace which isn't producing any carbon monoxide. The walls of my condo are not insulated and the windows are drafty. I will open the kitchen window and turn on the fan when I use the oven. Other than this, I think my chances at carbon monoxide poisoning are zero. ... show more
