Review on 🔒 Safe-T-Alert by MTI Industries 35 Series Dual LP/CO Alarm - 12V, Flush Mount, White, 6-3/8" Width x 2-7/8" Height x 1" Depth by Brandon Teitel

Fairly easy to install, needs a couple of wire nuts for not bothering to include them. But like others have said, it breaks down pretty quickly. Purchased May 2019 with production date February 20th 2019. It is November 2021 and it will flash and beep when service is over. Warranty sucks. No Answer. Revain has a fully comparable version from another manufacturer (PANGEA Digital Propane Detector for Caravans with Loud Alarm 85dB, 12VDC, Trailer, Motorhome, Bus (Flush – Black)). Check the What Others Bought section. Reviews are better and cheaper. The only downside is that it's only propane and no CO if you need both.
