Not a single issue
Work's perfectly on most flat top and angled bangers, pretty sturdy as well. I broke the first one after a couple years and just bought another, they're perfect for $10!
Grate but not what i expected
It was a grate product over all amazing the only problem was it was way to big for my attachment maybe they can specify the size of each carb cap to better choose the proper one. Everyone has a diffrent attachment for there dab rig so 420science you were 1 star away to beeing the best
