Yes, your order did ship Saturday as did MKs and several others. We have adjusted our production schedule to shipping two batches a week, one on Monday/Tuesday and one Fri/Sat. So far that is working with orders not much more than a week out(from order received til shipped). We have always tried to keep our turn around no more than that. Makes for extra busy here in Zapville sometimes but keeps customers happy. I do not like to owe money so when I get some, I pay it off as quick as possible.
Yes, tube tips are made of brass with a stainless screen held in place with an internal retaining ring. The tubes are made from commercial grade nylon tubing. The tubing is very tough, Stems can be boiled for cleaning after dissolving stuff in some kind of solvent(we like 160 'shine). Just do not let the boiling pot run dry or they WILL melt.
As for heatport burning human parts, etc, we recess our heatport into the wood around 1/4 to 3/8 inch from the top of the wood. Kind of hard to burn yourself but not impossible. HappyCamper is right in that it is mainly a not so smart user issue. For sure influenced by what goes in the stem tip.
On that note a story from the past. This has happened more than once maybe because we have lousy instructions with our package(soon to be changed along with the website)
Got a complaint from a newb customer. Just could not get the thing to work. Pre-heated fine, packed stem medium, etc, etc but no vapor. And what you say Zapman, thought this thing only took a match tip worth of goodies???? And how do I get the herb out? And why do I get herb crumbles in my mouth????!!!! Yes, they were filling the stem portion, not the tip. Did have the tip in the heatport though! Quite a vast array of folks out there, the public. Needless to say, that was an easy fix.
