This one beeps after 30 minutes with the same CO2 warning of 061. Always the same number. Started on Sunday, the 30 day return window. Have another unit exactly the same make and model. They are plugged in outlets 4 feet apart and the 2nd unit does not have any warnings. For $70, think they should last more than 32 days. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Every one should have one as well as a smoke detector. *by P***I on Reviewed in the United States on March 4, 2018* Have had this Universal Monitor in use for the past 10 yrs and it has served its purpose. Twice it has alarmed when there was a problem that could have been dangerous situation. I highly recommend the use as it serves a double duty. ### ⭐ 1.0 out of 5 stars Faulty! Don't buy *by G***R on Reviewed in the United States on March 28, 2020* This company makes faulty detectors. I recently had one go off indicating a carbon monoxide leak. I immediately called the fire department and upon inspection of my home, I was told there was no leak and that the detector was faulty. I'm calling the company and demanding my money back. This is disgusting.Update: Company offered me replacements.... I blatantly responded to a reps email asking her why would I want more defective crap? I am now up at 1:30 AM because the 2nd one I bought started beeping. We didn't call the fire department but replaced it with a First Alert detector we had and so far, no beeping. This is unacceptable and I'm going to get to the bottom this somehow with reporting them to the proper authorities. This is insane. ## Frequently Bought Together - Universal Security Instruments MCND401 M Series Plug-In Carbon Monoxide and Natural Gas Alarm with 9-Volt Battery Backup - Kidde Quick Connect Smoke Detector Adapter Plug, Smoke Alarm Wiring Harness, Compatible with Kidde Hardwired Smoke, Carbon Monoxide, & Combination Smoke & Carbon Monoxide Detectors - Amazon Basics AAA Alkaline High-Performance Batteries, 1.5 Volt, 10-Year Shelf Life, 36 count (Pack of 1) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/16645273-universal-security-instruments-mcnd401-m-series-plug-in-carbon-monoxide](https://www.desertcart.pl/products/16645273-universal-security-instruments-mcnd401-m-series-plug-in-carbon-monoxide) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-22*
