Review: Good quality - This is nice
Review: easy to install, works as expected - I installed the sensor in a 30 year old and small RV. biggest challenge was to find a good locations in the limited space. The instructions provide some guidelance regarding suitable locations in RVs. The installation itself is easy, cut out some wood panels, connect wires, done. I did a test run with propane gas, and the alarm sounded as expected. Note that the sensor is good for five years. Also note that it draws I believe 90 mA from the deep cycle battery. I will install a switch to turn it off during RV storage when the propane tank is closed to avoid battery drainage.

### ⭐⭐⭐⭐⭐ Seems to work great

Had to replace an EOL (end-of-life) detector in a motorhome. Installation took a couple of minutes and it seems to be the exact replacement for the previous unit.
