I am not so much "taking it personally" as tiring of all the anti-Smok posts based solely on something read on the internet. Many of those negative posts result from issues unrelated to defective Smok products....see my next comment on the post you quoted.....
The poster calling the GX2/4 "a huge piece of crap" because one atty didn't screw on or work and after dropping it, "it died?" I have no idea if that poster ever followed up with any updates, but I don't think those "failures" justify advising others not to consider buying whatever mod it was. Marking my post with a disagree, then quoting my post to proclaim "for that reason I wouldn't suggest it" leans heavily to that "advice."
Does op need a new mod? No! But since the title clearly states a frustration with limited battery life and the first post contains "Guess I'm have to find a 4 battery mod or.....", suggesting my post was on topic and within reason. Of course, op has the option of altering his vaping preferences by upping the ohms and lowering the watts as others are strongly suggesting.
Hey, that's me, lol. I have a bunch of other mods that I've purchased recently . .a Therion 166, an eLeaf pico, an Innokin Kroma-A, a Smok G150 . .a mi-one . .plus I have a box of older mods that I purchased a few years back. It's not like I have nothing to compare to.
The drop that killed my GX 2/4 was just a few feet onto carpet. In my opinion and experience in dropping mods . .that drop shouldn't have killed the mod. Even before it died, I was pretty sure the fire button was going to break . .after about a week it started feeling "weird".
As far as the G150, that mod is still working but it acts strange when I charge it. Sometimes it takes a very long time to fully charge, sometimes it stops charging before it's fully charged. Coincidentally or not, I had one charger burn-out while charging the G150 (not smoking or anything, just died). I'm too nervous to charge it unattended and it takes a pretty long time to charge so it doesn't get much use. The other odd thing it does is it always reads the resistance differently . .ie . .if I remove the topper and put it right back on . .the resistance will read as much as .5 ohms difference. Periodically during use the vape power will just drop right off .. then I'll remove the atty and replace it and all of a sudden it's good again.
I'm definitely have no "anti-smok agenda" - it's just based on my recent experiences with both the G150 and the GX 2/4 I would not purchase another Smok mod. Tanks yes, mods no. That's just me, my opinion, my experience . .yada yada.
