I’m cringing so hard seeing that glass peice on the left 😂 that’s how one of mine broke

And maybe a stabilizing base for the new one

Feel like it could be the fact the fab egg holds more water so the hit is percolating through more water thus making it a smoother feeling hit!

I've upgraded my glass. I haven't noticed a change in 3d chamber temp. I have noticed a cooling/smooting of the temperature inhaled with better glass...and no water bubbles in the mouth. I'd do it again if I had the opportunity. YMMV, the above is a sample size of one, offered hoping to help.
