I haven't noticed the tip on my i30 getting hot, but then, it's not my daily driver. It sits on my Vamo when it's not being used as a dripper, and mostly just sits on a shelf waiting for me to take an occasional toot on it. I always have a REO in my hand, and 95% of all my
vaping comes from those.
Now, the tips on the REOs get hot from constant use, which is why I usually have glass tips. They seem to dissipate the heat quickly so even when I chainvape - which is most of the time - they don't get uncomfortable. The downside to glass is that they tend to build up the lip shmutz pretty quick, and I have to wipe it off a lot.
