Carbon Monoxide Detector/Propane Detector

Ordered this item to replace the original in my RV which was 5 years old and at the end of it's life cycle. It is identical to the original. Perfect! Thank you Anchor Express!

Right Part, Fast Delivery

As the title suggests, the proper part arrived as ordered and on time. The price was very competitive and the installation is simple (two wires). But who would have known that these devices last only 5 years? Not me.
