The device works as advertised and is simple to use. First thing I did was test it on my gas stove to confirm it worked. A friend called last month telling me they were worried they had a gas leak. It was so great having this on hand where I could drive over to their house and check it out myself. All is safe and I'm very glad I have this for use when the need arises.

Worked as Expected

I used this when I refurbished my weber gas grill and replaced the gas stove's hose to make sure I had replaced everything well. The device was well packaged and the instructions were good. Don't forget to allow it to startup for 30 seconds in a "gas free" space
