It is useful for my RV. I will buy two and give one to my mum.

I like the dish soap check always work. My dad told me to never to the lighter check.

Well done! I will have this one.

Hey keep them coming thanks really needed this help

I never knew there was such a tool! My dad told me about the dish soap, that's what I've always used. I'd be too afraid of the lighter test😂. Gas makes me nervous. That tool is on my Christmas wish list. Thanks!
