Re: KM or MZ for first hookah
They smoke the exact same way.
So it's based mostly on Aesthetics. In my experience, i have notice KM welds are not as good as MZ welds. I have not yet seen an MZ with crappy welds, but i also have seen some KM's with great welds. Hence the reason i trust MZ more when it comes to hookah longevity.
You are getting quality either way, but i would say MZ has more quality control. I'm sure a reputable vendor would snap pics of the welds and send them to you though. So price would be a big decider as well.
