A warmer vape will result in a "stronger" flavor. Think of ice cream for example. We eat it semi-frozen and it's just sweet enough, but let it warm to room temperature and it becomes overpowering with sweetness. The same thing seems to happen with vapor. I like a cooler vapor and I do notice a difference in flavor between a clearo and a T3 using SI RY4, but then they're both different, stronger, than a CE3 or carto. Looking at the whole picture, I like the T3 for flavor, vapor and not needing to fill it very often at all. Next up, for me, is the CE3 for flavor and vapor plus the real convenience of being able to use it no hands on an auto 78mm.
I haven't run into the gurgling that some have been reporting. I've been using Kangers for over a month and an SI for over a week now. They do "pop" a lot as the liquid wicks in and hits the hot coil, but that happens with the CE3 as well and makes me think it's a characteristic of bottom coil devices. It doesn't seem as noticeable in a carto, I think, because the filler mutes the sound, but I have heard it from them as well. Every once in a while I can hear it on a clearo. Have any of you who are reporting the gurgling tried blotting out the air tube with a pipe cleaner to see if it's actually liquid or more like condensation?
