Great heat retention, sides of the banger remain within 30-50 degrees of the bottom, one of the best I’ve owned. Was cleaning it this morning after use, and it slipped out of my piece 3 inches above and broke on the joint, so just be careful, otherwise it’s an amazing banger

very strong banger , burns nicely thanks 420science /ALEX

Great item turned my milk carton by Grav into a top notch dab rig holds heat long enough forsome nice low temperature Dabs

works really well, I'm still trying to figure out the heat, but performs as advertised. Definitely will buy again!
