I guess it's your opinion if it's worth it or not. I have noticed that I can reduce the dial by about 3. So I went from about 1 the on dial back to about 10. Also, the heat holds through the full draw, no taper at the end so your full temp the whole ride!
Hope this helps!
How does it change temperatures? Are you referring to the bead mod? I don’t want to do that and I’m not sure it needs it. I just want to make it easier to clean and not mess with a screen.
