I do not quite consider myself EXPERT of anything.
Though I will admit to having a good "working knowledge & awareness" about a great deal of subjects, vaping & using mechanical mods included. I do meh, okay at it.
Do agree that around 0.20 (R) oHms coil build, be that single coil or net resistance of the whole build eight to twelve coils ... is a good safe area. I usually attempt staying right around there. My wife rather I stay around 0.30(R) but will let me dip to the 0.20(R).
Well, I can appreciate your opinion regarding regulated mods over mechs. I may disagree but only as a matter of preference, subjectivity. I like using RDAs but do not desire to continually deal with dripping. Ergo, I squonk. There are no currently available regulated mods for squonking within the $50 USD or less price.
The only exception to that might be a Pico squeeze but I think it only uses a mosfet like the Kanger version 1 Dripbox. Those I do not consider 'full on' regulated. To me full on regulated means it has a chipboard and hi fangled circuitry. Besides not being under that price point, if the electronics fail in a regulated mod, unless you've a bit of education in electronics you may be left with a useless 'brick'.
So in my opinion, and that's all it is, I prefer using a mechanical over a regulated mod and see doing so having value & merit.
I still do respect your opinion though. Also agree that mechs ought not be shoved upon newbie vapers. Let them gradually come to them if they so desire, no need to disparage regulated or mechs. Both routes follow the same path.
For the OP and original question, ...
It is not about any specific brand exploding more so over other specific brands not exploding. The point is to acquaint yourself with some basic understanding of the process you're using in vaping, then, applying good sound common sense to avoid risks. Barring that well, you can be one of vaping's crash test dummies and go blow up any brand mod or battery you desire. If that seems harsh consider that it is what it is. I still will continue vaping rather than smoking.
