Micro is the diameter of the coil and the loops ARE touching. The idea is more wraps touching gives more contact with the wicking which gives more contact with the juice which gives more vapor. At least that is how I understand it.
The other 2 videos are probably traditional coils probably with silica. Those do not touch.
Edit: Both work fine. I just personally prefer the micro for ease of setup, ease of use, flavor and vapor production. That is a preference not a rule. Try both and see what you like.
Thank you Mirany, that helps. I wasn't understanding the difference in the 2. I wondered if you HAD to use a reg coil for Xtopper but only a micro for XXtopper, ya know? Is there any that require a specific coil or can you use either reg or micro in anything?
In 1 video, it said if the coils touch it will cause hot spots. I'm guessing that is only if it touches in 1 spot and if they are all touching, pressed together, that's not the case, like it's a giant hot spot.

Because I prefer a cooler vape, would I probably use a reg coil as opposed to a micro? Is the micro warmer? I have 2.2ohm heads in all my glassos, I don't like the warmth of 1.8, so it would seem to me if the micros are warmer, it might not be a good idea for me. Or does it only get warmer with the lower ohms and not the coil build?
I'm sorry I'm asking so many questions, I really want to figure this out.
