I honestly don't know why people use the 3-piece models. I've never gotten one to work well for more than a few drags. I love my KR808D-1 and am reluctant to try anything else.
I tied a couple different ohms 2 and just a regular one which measures out to 2.5. I will give them a shot again on my next order this time in a higher ohm. I'm also thinking of trying larger carts because of how good tehy are working for me,. Like I said I hated carts/attys on my 510s/egos.mudboy might need to try carto with higher ohm's on your screwdriver it'll run cooler.
I don't think my experience is exactly typical, from what I have read on here...
But cartos last me two or three drags and then I start burning the filling.
Since I was a HEAVY smoker and vaping doesn't exactly match the experience, I find myself vaping near constantly much of the time which meant changing cartos every few minutes. Admittedly, with 6 cartos in rotation by the time I got to #6 the first one was good for a drag again, but...
Yeah, two piece wasn't enough.
The three piece I got was better, but not by much.
A liquid feeder, on the other hand- no polyfill or foam to burn, a much larger amount of fluid and long battery life.
That is what it has taken for me to be satisfied.
I haven't tried cartomizers, but I don't see the point. I imagine they take up at least the same amount of space as a cartridge, so if I want multiple flavors I gotta carry around a bunch of cartos and a bunch of bottles to refill them. Plus if the atomizer part of a carto burns out, what happens to the juice that's left inside?
Anyway, while they might be a little more convenient than carts, it just seems like more hassle than I need. Plus then I hear about this condom refilling crap and using syringes... Screw that. I just screw on a drip tip, grab a bottle, and get the hell out the door. When my e-cig runs dry, I drip another couple drops in it. Very simple. I'm interested in finding out how well that new 510 atomizer with juice reservoir works. That I think I could do, depending on how it works and how WELL it works. But for now, I just drip. The way I see it, I can either carry condoms, paper clips, juice bottles, paper towels, caps, and a bunch of cartos or carts depending on which I'm using, or I can eliminate the need for all the BS and just carry juice bottles. And with the cart/carto options, if i'm not carrying juice bottles to refill them, then I'd be carrying an assload of carts/cartos. I don't feel like having the things just floating around loose in my pockets, and I don't feel like spending money on a cigarette pack-sized PCC or some stupid camera case that I need to carry everytime I leave the house. That is why I use a 3 piece system. I drip. It tastes great, and it's the lesser of 3 evils, I feel, as far as the pain in the ... factor is concerned.
And there we have one of the good things about the current PV market: devices to suit just about anyone:
2 piece
3 piece
drip
liquid
and more exotic stuff too!
And to answer deback:
in an empty E9 carto I can get 16 to 18 drops of juice.
And if I don't top up after 3 drags I will be burning filler by the 7th.
There are much easier ways to use cartomizers than what you described. Personally, I don't want to take the extra time to be dripping constantly. When I drip, without using the pita cartridges, I have to drip 3 drops every couple of minutes, and there's usually some liquid on the outside of the atomizer, which ends up on my hands.
I also don't want the inconvenience of using the pita cartridges and fillers inside, so I don't use cartridges.
If I'm gonna have to drip, I'll just drip the juice directly into the filler of the cartomizer, and that carto will last me at least an hour, with constant vaping. That's how easy using cartomizers is. I don't have to drip every few minutes or mess around with a cart filler or mess around with modifying a cart filler to make it work right.
I don't have to drip 3 drops every couple minutes. It all depends on how much I use it. It leaks sometimes, but so do cartridges. The way I see it, dripping requires me to carry less BS around with me. Instead of carts/cartos and juice bottles(plus other stupid crap like paper clips for messing with cart filler, and condoms/syringes like I keep hearing about with cartos/carts), I just carry the bottles. All I need is my 510 unit, a bottle, and a PCC. with carts and cartos you need all that too, but then you need extra crap. and I never have to change my drip tip or worry about using up all of the flavor in a cart/carto. If I want another flavor, I just drip that flavor. It's the least possible hassle for me.
The 3 drops every couple of minutes is when vaping constantly (like about 5 to 10 drags, depending on how long one drags on it). Sorry that I didn't clarify that.
I understand what you mean about carrying lots of stuff, but now that I've been vaping for two months, I've got it down to (when I go somewhere and will be gone for a while) just taking two batteries (should only need one, though, but take an extra just in case) and a little box that contains 8 cartomizers. I don't have to drip when I'm gone; just screw on a carto when the one I'm using gets empty.
I don't take any PCCs, bottles, carts, paper clips, q-tips, condoms, syringes, or fillers. Just 2 batteries and a box of 8 cartos. Here's a picture of the box that I bought from Walmart (three little magnetic boxes, with plastic windows, that hold eight cartos each) for $3.88, and can be found in the Office Supplies area. The original purpose is for paper clips, tacks, etc:
