With Solo 3 I also have the feeling that the temperatures are a little higher than stated.
I often vape between 185 degrees and 205... Rarely at 220 degrees.
Most of the time I use my bong and it's always 205 degrees to rarely 220 degrees.
Lately I've been having temperatures at 220 degrees a lot and I've noticed that I'm actually burning my weed.
The material is black on the top layer and I always make sure that there is a gap of 1 to 2 mm.
I also noticed that in my glass bong, as soon as I set it to 220 degrees, I got yellow deposits pretty quickly... like with tobacco smoke, in yellow... It's not as extreme as with tobacco, but I do it very often When I was cleaning, I noticed this.
My glass/bong adapter also turned dark yellow at 220 degrees after 4-5 pulls.
I have the feeling that the temps are about 5 to 10 degrees higher... Maybe even more... But I can't measure or prove it, it's just my feeling.
But it's not a bad criticism... I'm still very happy with my Solo 3 and I'm always discovering something new after 6 weeks
