The G4's are absolute junk. I mean serious junk.
Maybe they'll improve the design, but I can't believe they even introduced that product to market it sucks so bad.
I bought a 5-pack. The first one leaked a third of the juice all over my PV when I left it alone for an hour to make dinner, and it was standing straight up.
The two I tried after that both got juice up in the center 'straw', which completely ruins air flow and vapability, and I was just
vaping as normal, nothing out of the ordinary. This was just by
vaping, not by getting it in there when filling, which I used a syringe for.
Total junk product, I threw the rest in the trash.
It's a nice design, I hope they improve it, but as-is, should never even have been released.
The Smoke Tech dual coil cartos are great.
They work exactly as they're supposed to, vape great, hit great, good flavor, I'm totally sold on them.
They last an average of about two weeks (IMO), which is fine with me for a $2.00 part.
The only thing about them is that to really fill properly, you need to use a syringe.
You can top off by drop filling if you're out and about, but at home, I refill with a syringe to really fill it properly.
Besides that (which isn't even a criticism really), I give them a 9 out of 10 and am quite happy using them on my 3.7v.
