The horizontal coil is far superior, from what I understand.
It was designed by a long-time vaper (Leaford) who was hired by Bloog.
I believe Leaford first moved to China after being hired by Vapor4Life.
And then he moved on to Bloog where he helped develop the horizontal coil cartomizers.
If any of this is incorrect, please feel free to correct me.
I hate spreading false information.
Not sure if I can post here, but here goes...
Sorry to resurrect an old thread but I just came across it and want to correct a bit of misunderstanding I see too often. I did not design the horizontal coil cartomizer. I never said that, but some people have taken what I said that way.
I said that I
contributed to our manufacturer improving the 808 cartomizers, but not to great enough of an extent to claim that I designed or developed them.
I was requesting a more burn-proof carto, and I suggested extending the burn-proof fiber air tubes the length of the carto (they were previously just above and below the vertical heating coil leaving the poly fill exposed to the coil) to insulate the poly fill from the heating coil, and to act as a chimney, concentrating the heat for hotter vapor. But I didn't suggest a horizontal coil, and my idea wasn't acted on at that time.
Later, without my involvement, the engineer I had discussed that with added the horizontal wick to my full length air tube idea, and created his horizontal coil 808 cartos, for which as far as I knew I was the first, and for a while the only, customer. (A friend of mine now claims that he was buying them before I was, but I was working with the manufacturer for months and never saw any packaging for them but mine, until he visited China and I started seeing his.

Who knows? Who cares anymore?)
My manufacturer may well have gotten the horizontal coil idea from the 510 or some other model. I really wouldn't know, but wouldn't have a hard time believing it. The guy is a great engineer, but he does tend to perfect other people's ideas more than create his own innovations.
