Shipping to US is €45 ( tracked National post)
Make that €30 for packaging& shipping to US (depending on customs arrangement) 
I received a few questions and it seems I should clarify things for people new to this.
"Injector" refers to the Quartz Thunderbolt itself- the heater unit.
It is a term referring to this type of vaporizer design: a heater tube that joins with the bowl from above, and heats up the air entering the bowl as the user inhales, offering pure convection, high density vaporisation.
I don't like the term "injector" but it is what we have for now- I'll see if i can stop myself from using it..
The bowls I am offering in white, amber and fumed silver ( other colours may be possible at a small extra charge) all have a 14mm male joint at the bottom. A cheap low profile adapter will work to attach to a 19mm female joint.
The QT comes in 19mm and 14mm sizes, with matching bowls (optional).
WHICH SIZE QT TO GET?
14mm= less gas, more efficient for smaller amounts, more suitable for j-hooks/dry pieces, small bowl - hard to replace bowl if you break it.
19mm= bigger hits, large bowl, easy to replace bowl - more gas and herb consumed.
PLEASE LET ME KNOW WHICH SIZE YOU WANT WHEN YOU CONTACT ME ...
The small batch of QT's and other prototypes being made is delayed, but it is a matter of days now...
Here's another detailed look at using the QT (prototype shown)
For the lucky ones to be getting started with their QT soon, here's a few quick tips perhaps not covered before:
-Do not overheat- do not attempt to get the QT red-hot. Do not heat the QT empty or without quartz, ruby or SiC balls inside! Other materials have not been tested - use them at your own risk...
-Do not use metal balls. Spare quartz pebbles are added with every order and they can be cheaply replaced. If you buy the QT pre-filled, the only worthwhile upgrade
might be replacing some quartz with SiC balls- (prepare to pay almost $1 per ball !)
-To use with a bubbler (recommended), first test the water level : attach the loaded bowl and the QT, and test the draw. Add/remove water so that you can get as much water in there as possible while still being able to draw as hard as you comfortably can, without getting water in your mouth. This is essential for getting the full experience!
-Don't compress the herb in the bowl. Just press it down lightly to get an even, flat surface.
-Instead of a chef's torch, a 25mm axial coil can be used ( see video above) with no modifications. This design is not optimal for this, however, and you would need to get the coil red-hot to achieve a moderate vaping temperature in the QT. A coil - based version is coming soon with the Thunderbolt 202.
- Attach QT to loaded bowl and
fire at the gemstones only, and away from the bowl, while holding the bowl from the bottom and rotating it on the joint. Very slightly lift the bowl off the joint to enable easy rotation. The use of a torch with a slightly upwards angled nozzle is recommended.
Keep the most intense part of the flame off the quartz and use as fat a flame as possible (wide instead of focused).
-For easy firing, set up your torch or bubbler with coasters or other props (if needed) so that the torch can fire at the gemstones when standing next to your rig, and rotate the bowl/QT assembly as seen in the videos. Do NOT leave the torch firing at the QT unattended!

-Use a medium- high flame to get up to temperature within 60-70 seconds or so. Taking too long heating up the injector attached to the bowl will heat up the bowl, potentially leading to some loss of flavour and eventualy to charring or combustion upon inhalation.
- Pay attention and
stop firing when you see the rubies go dark. They will look almost black in low ambient light but only dark red in bright light.
- I recommend trying a faster, deeper, but shorter inhalation than you may be used to from other flower vapes. The mass of gemstones will release the heat they are holding as you inhale and you can zap your load with a quick blast of hot, quartz-energised air to receive very tasty clouds of pure vapor.
If you don't get enough vapor, you know to fire a little longer (a few seconds) past the colour change. This depends on your glass piece and how you like to draw on it.
The harder the draw, the higher the temperature needed, and conversely a lighter inhalation requires a lower temperature to avoid charring the herb. Effects will differ depending on how you hit it.
That's all there is to getting started....
