Some say that the dual coils provide greater heating area so you get more vape for less 'on' time - others say it's easier to burn the juice if running at higher voltages.
Personally, I have gone back to single coils as I find the performance to be more consistent.
Ultimately - YMMV. If it works for you then it's good.

A lot of people swear by DCs. Personally, I got a very warm, humid vape out of them that I didn't care for. For my taste, single-coil Ikenvape Fushions outperformed them up one side and down the other.
A side note is that due to their large current draw, some devicessuch as first-generation Lavatubeswon't be able to deal with them.
In the end, If you were hoping to get a definitive answer as to whether you'd like them in advance of actually spending the money and trying them, the answer is: sorry, pal. This is one of those questions only you can answer.

Here's a post that tries to explain the electrical differences between single and dual coils.

Dual coils use two coils that are a higher resistance, for example, two 3 ohm coils, to achieve a low resistance vape, in this case 1.5 ohm. The idea is to get the increased heat and vapor off of two coils while not burning. They are typically longer (XL) and can be bigger diameter (mega) to hold more liquid. They burn more liquid than a single coil and use more energy in order to give a bigger vape, and can't be used on the small 510 batteries.
Single coils are more often the standard size but longer ones are also available. In order to get a better vape on standard 3.7 volt devices, single coils are often used at 1.7 - 2 ohm (LR). They can burn a little more easily in my experience but are great in a tank where they are consistently wet, reducing the chance of a burn and increasing capacity. They will also work on a smaller battery.

I never had any luck with the EMDCC's with my KGO for some reason, just doesn't taste right to me. I stick with the single coil LR.
Do dual coils need a certain voltage?
I swear by them lol. Really for what it's worth on lower voltage I don't get any real difference between a 1.5 DCC and a 1.7 single. I personally haven't had any luck with tanks, and thanks to the ePower DCC and XXXXL I have other options...other options that vape quite well.
There are a lot of people who say DCC isn't worth the time unless you're vaping them at 5 volts.
I enjoy all DCCs (1.5) at 3.7 volts, my previous post does cover the voltage, but I did want to put out that 1.5 dcc on standard 3.7 volts works fine for me. Like any other carto/juice/PV personal preference reigns supreme.
It's strange that the Lavatube got a whole lot of hate because it cut the voltage on 1.5ohm DC cartos to 3.7V. People said don't use DC's on the Lavatube because they won't work.
Then, those same people will talk about how good DC cartos are on their 3.4 or 3.7V PVs.
The same vendors who will recommend a 2ohm SC Boge for your kgo, and who tell you that 3ohms is too high, will tell you a 1.5ohm DC works good on it.
Huh???? That makes absolutely no sense whatsoever.
Fact is, If you're happy with a 3ohm carto on your 3.7V PV, then you'll be twice as happy with a dual coil.
If you like 4.5 watt vapor (or cold fog) so much that you want twice as much of it, go for a DC carto at 3.7V.
OTOH, if your "sweet spot" is around 7-8 watts, like most people, then use a 1.7-2ohm single coil carto.
If a 3ohm coil at 3.7V is not good, then having two 3ohm coils at 3.7 isn't going to make it better.

A first generation Lavatube deals with them just fine. They draw the same current a single coil would and the Lavatube just cuts the voltage to them to 3.7V. Vaping them on a Lavatube is exactly the same as vaping them on a kGo or any 3.7V PV.
I don't understand how 4.5 watts is warm just because there are two coils at the same time. If one ice cube is cold, two ice cubes don't make hot. A single coil 1.7ohm is 8 watts. How can that be not as warm as 4.5 watts? What kind of voodoo hoodoo is going on here?
I have a feeling that if 1.5ohm DCs were called 3ohm DCs (which they really are) nobody would like vaping them with less than 4.5 volts, just like nobody likes 3ohm single coils on less than 4-5 volts.
To the OP, if you want to see how 1.5ohm Dual Coil cartos will perform without buying them, take two of your ego batteries, or whatever you're using, and tape them together. Put a 3ohm carto on each one and vape them at the same time. That's what a 1.5ohm dual coil would be. That's what they are.
I lol'd.
I didn't like the 1.5 dc on my kGo. It would probably vape better at 3.9v or s/thing which since the only VV mod I have is the Lavatube, I can't try it out. Sooo I stuck it on a 5v passthru.
lol At least I could get some use out of it.
Unless you vape between 5-7.4V's, I wouldn't use the dual coils. They really shine at the higher voltages and stink below 5V.
If you're using a 3.7V device, stick to around 2ohm Boge carto's or low resistance atomizers.

Hehe... Sailorman! I'm so glad I'm not the only one...
You are so right! Those dual coil cartomizers are tricky, and I stopped using them because they are nothing but a gimmick! We're dealing with two 3.0Ω coils but only 1.5Ω total resistance. I don't claim to understand how those cartos work, but, as EvilGnome6 explained it to me once,:
"Ohm's Law cannot be defied. V=IR holds true regardless of the variables.
If you have two 3 Ohm coils, you have a total resistance of 1.5 Ohms. Let's take a scenario of a 4V device facing 1.5 Ohms:
4 V = I x 1.5 Ohms
I = 4/1.5
I = 2.67 Amps
If the battery can't deliver that much current something has to give. Since it can't magically increase the resistance of the coils to keep the voltage constant, it must result in a drop in voltage."
So, basically, if the battery doesn't have enough amps, it will just drop the voltage... So what's the point? You're still vaping at 3.0Ω resistance, even though you're vaping two coils at once, which gives you more vapor, but that's about it.
I always felt that vaping a 1.5Ω DC carto was like vaping two 3.0Ω cartos simultaneously! Twice the vapor, but the same Wattage... And very stressful for the eGo class batteries. Not to mention that it uses twice the juice and mows through your batteries like there's no tomorrow!
And the filler burns, too! I have pictures to prove it!
From the manufacturer's website: Current Protection - The unit is designed to monitor the current and shut itself off if it detects any excessive over-current conditions (greater than 2.5 amps).
Like everything else it become pretty subjective, and since everyone plays to a different set of drums, it's just personal choice.
I did not like DCC's mainly because I found that there are better ways to get the same approximate hit from my PV.
I like to run a heating coil in the 7-8 watt range, but in order to do that with a DCC, I have to ask the PV to provide 14-16 watts at between 3-4 amps, and I just don't like going there with my PV's. To me it's no different than putting a LR atty on a mini bat.
