Correct, it's not the moniker, it's the originator.
I am fairly certain they are vertical, but I do not know for sure. I will ask.
For the wet, it is using a fill so keeping them wet will not be as critical. That said, all cartos work better when they are full all the time. Personally I do not let mine ever get down to the end, I refill Go-go carts all the time way before they could be empty and that I think helps keep them alive and free of gunk longer.
In case you wanted to know the horizontal vs. vertical for other reasons:
Here is my opinion on the subject
From a purely uneducated view, and when used properly, I do not see how a vertical or horizontal coil would make any difference whatsoever. I know there have been discussions about it and many feel the horizontal are better, but again in my uneducated opinion, that is due to confusion of cause and effect with a pinch of enthusiasm thrown in.
A company that makes a good vertical, will also make a good horizontal and vice versa.
If a company has a rep for a good vertical coil and then comes out with a new improved horizontal coil the psyche relates it to being better, even if it is exactly the same as the previous and in turn the enthusiasm for them spreads from person to person and a "good" could becomes a "great" and more desirable coil even though it's the same.
As an "insider" I know that these companies put out the same stuff and relabel them to generate buzz and interest, just last week I received a few price lists with the exact same thing in them labels as improved with new names
Again, my opinion is basically armchair electronics here, I do understand the mechanics, but I am not an expert, I just do not see the difference between horizontal and vertical in terms of one being better than another (when used properly and keeping them wet). I think it's misplaced perception spreading from one person to another.
If anyone knows a proper reason one would be better than another please educated me
As others have said and I have found over the months to be a true virtue of the Go-carts is the horizontal coil. Some don't take to rebuilding due to spotty coil control but I am proud to say I was one of the first followers of the Mohawkz Methods of rebuilding the Go-carts.
I have some that have been rebuilt so many times, I am not usre what vintage they are. Dual horizontals are made and like the single coils, are less likely to burn your filler due to the coils being at the bottom. So even if you only rinse and reuse, the horizontals are the best for repeated use.
The only problem I personally have found with using vertical dual and triple coils is that the same heat from 2 coils that gives you the warmer vape will also cause issues if you're a juice hog like me.
I tend to get wrapped up in whatever I am doing and if you let the upper most coil in a vertical dual get dry, they are toast. If they don;t actually burn the filler, they do singe it and give a funky taste. Kinda reminds me of back in the day when I used to smoke ands partake in adult beverages too far and would light a filter having the wrong end in my mouth.
Not bragging about being stupid but that is the taste a singed dual coil reminds me most of.
SO glad to see you here, I 'm Alice from the manufacture of electronic cigarettes in China.
That's too funny!
