Seems like every 10th to 20th hit nothing happens when I pull the trigger.
I have had that happen, but only rarely and have attributed it to my messed up hands. I've also wondered if it might be due to some "sideways" pressure on the trigger? Between those 2 possibilities, the rarity of occurrences is not concerning to me since it helps keep the wick saturated.
One other thing I've noticed is that I need much lower wattage compared to the Procolor or T-Priv. Usually had to run those close to 100 or over to get the same effect as the Mag. I think this is a good thing. Is anyone else noticing that as well?
I don't have the Procolor or T-Priv, but do have a couple other Smok mods. But I mostly run my Prince tanks on the Mag and BB or BBB on the others, so not able to say. And up until a few days ago, I was only running the Q4 coils on both my Prince tanks. As with other Smok tanks/coils, I tend to power them towards the lower end of the "best at" range. I always have the preheat set at "N" (normal) on all my mods, but you might check those settings.
Durability! Unrelated, but will add.....Despite my wonky hands, I rarely have any problem with dropping my vape. But, sure enough, I am up to 2 times with the Mag kit.

I bumped it off my desk (what, 30-32" drop) onto a chair mat over carpeting. Battery clip ejected, but other then that, no damage or markings. I guess, since that was not a tough enough test, I dropped it from chest height (maybe around 4'....OK, I am not over-tall

) onto concrete. Who knew that inside pocket of my winter coat wasn't a pocket at all, just an opening in the liner to access the real pocket.

Dropped the vape in there and it shot straight through to the concrete. Given its weight, lucky it didn't hit my foot....or maybe should wish it whould have and cushioned the blow? Anyway, it stayed intact, nothing broke, and only found one very tiny, barely noticeable mark on a bottom corner. So I am splitting my good fortune between luck and durability. And since I had commented earlier about how the grip made it more secure in my hands, good thing neither time was from losing my grip!
