Review on 🔒 Enhanced Safety with Flashback Arrestor, Regulator, Oxy/Fuel Combo by Michael Sharp

I think this is a good cheap safety feature. It's pretty rare for a flame to go into a bottle, but I guess you never know, I've heard of it. It works (I think). The strangest thing about his review is that no one (including me) has any idea if it actually works. I mean think about it, I've used a flashlight without it for 40 years and never had a problem, and since I installed it I still haven't had a problem. does it really work? not working properly, because most likely will die from the following explosion. It might be pure snake oil but who cares it's only $50 and it makes me so warm and fluffy. The only thing I can prove is that they don't leak (soapy water test) and my flashlight worked fine once installed.
