Review on Enhance Safety with Safe-T-Alert 35-742-BR Dual LP/CO Alarm - Flush Mount, Brown by Darren Cole

My Winnebago View was only 5 years old when my propane alarm started to fail. I received this LP/CO to replace the factory original. It fit into the original wall cutout and the entire installation only took about 15 minutes. Works well. I later read that these things should be changed every 3-5 years. I've considered not replacing the failed unit, but for security reasons, it's too important to ignore.
