Zanbo Gas Leak Alarm Detector Natural Gas Leak Alarm Sensor with 12V DC Connector Gas Detectors for Home

I got this as an extra layer of protection for my famiky. We have smoke & carbon monoxide alarms, but our range an grill are both propane, and I worry about leaks and burners not igniting right off. This unit makes me feel a little more assured when I am not avalible to check up on things.

I ordered two. Returned two. Got a refund for only ONE. NOT happy about this. It's been waaaaay too long to process both refunds. This item was not as advertised and would not work where I needed it to work.WHERE'S MY SECOND REFUND?????
