Now that you mention it, I do the same. Sometimes for a quick in-between rinse, I fill my mouth with water and blow it through the tube and out of the atomizer (never a wick in there, but sometimes with a coil, sometimes without), then just blow air through to get the water out. Once I realized I didn't care to meter as much, I started to leave it on.
So my next question, how many times have you EVER had a dangerous reading? I'm not talking about not hitting your preference, but a straight up this will murder my mod type of situation? If this has ever happened, do you think you would have seen it before if you really just looked a little closer? (I only collapsed one spring before, and it was because some extra leg wire was touching the side... totally could have seen if if I actually looked... now I always look, lol)
For me never lets face it its common sense if you have it you no better then to leave wires hanging or not trimmed . It can happen to anyone I suppose and using a meter is the safest option . I have never shorted a mod . I believe its because I have never been one to constantly mess with my set up . I no what works and just use it . I dont constantly change coils ether . I build a coil run it for a couple weeks .
