The scratch on my stem is at the little ball locking divot point. Because I stupidly tried inserting new stem in old Bowle, just too tempting not to try, like a toddler. Difficult pulling it out, thus the scratch. Can feel it with fingernail down to aluminum. Insertion "rail" marks already in puck. Been there, seen that
Hot ISO is a NO-NO, especially submerging stem with any surface scratches. Better to use room temp ISO inside stem, do the old thumb plugging, and shake. This is all old news, but thought I'd bore you with it again. Do not open the stem, no need, will likely strip screw head anyway
I'm in a 2 q-tip habit after dumping pot. First one to swab stem while resin still warm and hot pot cooling, second q-tip for pot. Can go for many months before stem needs iso shake IME and O. Most of resin accumulates below pot and in rear corner, q-tippable
Like others, not thrilled with the finish. But, I am thrilled with the firmware tweaks around draw sensing. (I use the press and release method, because my tremors get set off holding button down) Old Bowle was occasionally shutting off heater during draw, seemed very sensitive to draw variation/slowdown, lights going blue, grrrr. No more! So far anyway. I've tried to vary inhale and even paused for fraction of second...no shutoff, YAY. This was my main gripe from the beginning
Relaxing now, not feeling like I need to keep a steady firm inhale going to avoid the dreaded shutdown blues
For battery life testing, I was trying to draw like an "average" user, whatever that is. Started 6 draws per pot, but went to 7 near start of test, and increased draw duration. Longer draws are more productive, and I've been spoiled by ball vape results, so disappointing for me using level 3
Now I just start at level 4 and end there. Sometimes like to do the 23 second "Bowle Blinker"
