That sucks
@dos equis . I've got one GonG still in the rotation for more than a year. Don't think it's ever been off the nano for more than a week in that whole time (maybe 10 days once). Never have had any trouble with cracking/breaking even pulling one from my coat pocket in sub-freezing temps and having it on a hot nano in 5 minutes. And, really never worry about it with the newer heavier glass.
I occasionally heat sink for a couple minutes at pretty high temp (8.5 - 9 for me) with hash, but usually don't leave my glass on my nano. Leave the GonGs in the bubbler and pull nano, or stand the stem in a little holder I use. Maybe leaving them joined is contributing to your problems? Definitely shouldn't, but weird they're cracking like that on you.
I have broken some glass in my time. I can be a clutz, even stone cold sober. Glad I've had no issues with this stuff, but sorry to hear you're having so many.
On another note..... for those of you out there with a D020-W, have you tried hanging your e-pik on the mouthpiece? Gives that freaky ring of glass a purpose! Have tried hanging the e-pik on pretty much everything I use it with, but never really worked well or looked good with any but this IMO. Keeps it handy, prevents me from "losing" it 5 times a night and think it looks pretty cool hanging there. Very nice if you're prone to sitting back on the couch with nano in one hand, and bubbler in the other! Just lay the nano in your lap or on the arm of the couch, use your e-pic for a quick stir, and you can be back at it while never losing a beat.
@ataxian - get the adjust-a-bowl if you haven't tried one yet. You'll love it!!
@Snappo - I'm going to resist the temptation to comment on your meat smoking, but be careful dude! You made me laugh and cough out a nice hit.
