VERY quick and easy installation
This unit is an upgrade for my RV since the one I replaced was a propane only detector. As can be seen from the photos, I had to print an oversized mounting plate since the previous owner had cut the hole in the wall too large for the included mounts to cover. I only had black filament on hand, hence the two tone look. The mounting plates that came with the unit look good and should work fine for a normal replacement. The included snap connector made the wiring a breeze. Total install time was about 5 minutes not including printing a new cover. I would definitely get this unit again.

    If the function and actual quality of the device is at par with the amount of mounting parts they have sent with this alarm your set for the next five years and can sleep safe and sound.

    Tested the device with a{me butane and it went off so that part seems to work fine.

    Bought it in November 2025 and installed in our trailer. About 2 months later it started beeping as though there was a CO or gas detected. Nothing was on in the trailer and it was stored for the winter with no gas on! Disconnected it and reconnected in June 2026. It didn't beep for a few days then started again. No gas is on! When I select customer support on the troubleshooting page I get directions for a different device!

    All that and to top it off it has an always on bright red "headlight" that will probably keep you up at night.

    Don't buy this product!
