This was made in China.
The instructions cover this, but I'm pretty sure that it blinks as it is testing the air, and it turns solid color and beeps when the gas is detected. If you have a natural gas or propane range or furnace, you can test it there and see how it reacts. If you've already tried that unsuccessfully, try removing the battery (a reboot) and try it again. I hope that this helps you out.
I recently discovered a Gas Leak outside my house at the Meter connection. The smell was rather strong. I am 6' and held the Detector about 4 ft from the suspected leak and it did not respond. Granted this was outside and presented an open air situation and response. Inside, such as your bathroom is more confined and I would guess that the Detector would work if the Gas is as heavy as indicated when tested. Given the smell and the density as you described, I would not hang around to find out whether or not the Detector would work. In my case, I called the Gas Company and they dispatched a Technician right away to repair the leaking Joints at the Meter. By the way, the Detector did work well indeed when the Tech and I held it about 2 inches from the Joint. Hope this helps.
Mine is a natural gas detector. It is battery powered. It found the leak in a very short time. for the price it saved me money also.
You do have to be fairly close when checking gas lines, this is sensitive enough to pinpoint exactly which fitting is leaking. Marvelous tool and very durable, although I keep mine in the box......could not be happier with this purchase. I have a very old house with many closed off old gas lines, and I check them frequently.
