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.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!
