Review on Y201 Portable Propane Methane Natural Gas Leak Detector: Find Fuel, LPG, LNG, Butane, Sewer Gas Leaks with Sound & Visual Alarm. Flexible Sensor Probe. by Jermaine Krishnamoorthy

I would like packages not to be shipped using the US Postal System, only Prime, UPS, or FedEx. The USPS said the package could not be dropped due to lack of front door access. We live on a camper place without a gate, without a barrier in front of the front door, actually I was in the yard all day. The apartment seems fine. The instructions were clear and apparently written by someone whose primary language was English, easy to understand and concise. I immediately read the instructions, turned it on and waited for it to warm up. I went to the gas stove, turned on the burner without ignition and got the correct sound and light alarm. I checked every fixture I could get my hands on (I live in an RV with a 120 gallon tank in the yard). Weak, brief alarm on the pressure relief valve. Placed the sensor where the sewer hose connects to the ground pipe and got the expected audible/visual alarm (methane, explosive gas). Let's see how it will be in the future. Registering through the company's website was quick and easy with just 4 entries (name, email address, model, Revain order number).
