Then a mechenical box mod doesnt exist because you cant move the electricity without wires now you can in a tube because the negative is the tube but you cant have a box without wires so a mechanical box mod is a box with only 3 wires a negative wire that runs strait to the bottem a positive to the switch and a positive to the 510 and as for ypur statment before that its called paying attention in order for a battery to hit thermal runaway it must first get hot and i dont chain vape it i pick it up take a hit or three and go on about my life so there is no room for it to get hot enough to cause a problem
Mechanical and unregulated are two different things. Without a mosfet your device loosely fits the mechanical description but most purists consider anything with wiring in it to not be mechanical. I think the biggest thing he was poking you about was that switch. It is not how often you hit it, or how hard you hit it, that switch is a 6amp switch at best. It may have been advertised as being more or not. dunno if you checked. The risk with that switch is failure, and it is going to fail. Is it going to fail open? no harm no foul, pop a new switch in. Is it going to weld itself "on" while you pick it up for a short hit driving down the road? It could very well do so. You will rapidly exceed the temp limits and go into thermal runaway on your batts at that point.
Put a mosfet in man, couple of bucks, peace of mind. Hell, put a few in parallel and have a true ninety bazillion watt mod only limited by your batts and your lack of concern for this type of thing. Or not, it is your face and hands after all.

People use this type of mod you have all the time for subohming and things are fine, nothing bad happens until it does. People drive drunk all the time, by the grace of god nothing bad happens until it does.
Subohming is only as dangerous as a persons naivety or nonchalance
