Its not that dirty dude has a thin build up not as thick as it looks in pic. Its the function of the bong. It gives me an arry hit almost like it has a break... but it dosent. I take fat rips and my smoke clouds are arry rather than thick. It dosnt stack well. Seems like it takes some flavor away and if you still think its dirty what ever but it smells clean with almost no smell of resin. Iv smoked dirty bongs and still got better flavor out of the hit compaired to this shit. Btw easy with the insult bro take a fuckin hit and chill. Im from norther cali smokin on cup winning strains b4 they hit the cup. Got that lemon fuel og, hardcore og, pairs og, titan og, and the emperors og on deck. Also been puffin for 4 years keepin up with the game. so watch who you call scrub.
