the mini bong (10mm joint, height about 5") arrived today:
great with the Dynavap M18, a little less with the Da Vinci IQ (the taste is about 50% what it is without the waterpiece, the IQ is really great for a long sipping session with not too high temperatures).
Tried it with some improvisations on the Sticky Brick Junior: great result, i think i'll love it through a bigger waterpiece.
Same with the e-nano (i used a pipe mouthpiece to adapt the 14mm to the 10mm waterpiece, it works somehow but not very stable...): the enano is like the SB Jr a monster through water.
Now waiting for the Matrix 14mm joint to arrive (in 2-3 weeks...)
