I acquired this Youde IGO W6 as part of a delivery test of China vendors. I won't publicize which, but note that I am so disappointed in delivery times from China that I will likely never order from China again.
That being said, let's get to this attractive Rebuildable Dripping Atomizer.
The IGO W6 is a five post system that supports single, dual, triple or quad coil setups. The air flow is arranged for dual or quad coil, though.
You can see the air flow ring at the left, it's the gold tone ring. When the dual holes are used, that is for a dual coil setup. When the slot is used, that is for a quad coil setup. For single coil, use the dual hole and shift slightly so that one hole is blocked. For triple coils, use the slot and shift slightly so that it is partially closed. Again, it's your choice and fully adjustable so that you get exactly the air flow you want.
The first thing to mention is that the coil leg insert holes on the W6 are small, quite small. I have doubts that you could use anymore larger than a single 24 AWG gauge wire – and that might be a bit much to insert two in each of the holes of the positive pin. I also did not like how the posts were aligned, particularly the center post. The coil leg holes are inline with the four negative posts which makes it nearly impossible to properly insert a coil leg of any length.
I decided to abandon my usual 0.8 ohm coil build in favor of using 1.5 ohm coils that are welded with a non-resistant leg. There are made of a 32 AWG gauge wire and made it easier to get access to the positive post pin and still keep the setup as a vertical coil.
Also at the right, you can see the amount of cotton I used for wicking. Doesn't matter whether you use the short posts or long posts, these are a good distance form the coil base. You'll need a fair amount of cotton to wick the eLiquid to the coils. I used one single cotton strand that that was quite long, inserting one end in one coil and the other in the second coil. The bulk in the center, I made sure touched the bottom of the coil in the center. The ends wrap quite nicely around the base as well.
Before wicking, I pulsed the coils and was quite impressed that I had all the legs the same length – both coils fired simultaneously and glowed from the center out. Ideal! After wicking, I saturated the wicks and the coil base right to the lip of the well edge. The well, by the way, is 1.4 mm deep. My ohm meter showed this dual coil setup to be 0.9 ohms. Good to use on a mech and on my IPV V2.
Out of all the dripper atomizers I have tested, the IGO W6 produced the best flavor and best amount of vapor. This is a cloud machine. With quad coils, this would be a weather system of its own.
At the left, you can see it on my V3 Flip. None of the Youde dripping atomizers include a drip tip. The one you see is my personal favorite, a clone of the Caravela drip tip with a laser engraving.
So, what's the verdict? Is it worth it? I am not disclosing the price of this IGO W6. You'll have to shop on your own for that – but at the right price, this is a good atomizer. I only gave this a 7-star rating, though, because of the positive pin post alingment should be offset by 45 degrees and all of the post pins should be larger. It's still a darn good atomizer with a little bit of extra fiddling.
UPDATE: September 25 2014 ... please note that I made a mistake in describing the coil that I used when building the W6. The coil legs are welded to the coil in a design that is non-resistant wire legs, and resistant wire coil. My apologies for confusing a few folks out there. And, by the way, the non-resitant wire legs are fused to the coil and since the legs are non-resistant wire, they do not increase the Ohms in actual use so the leg can be as long as you want it (meaning the distance between the posts and coil).
