To all the new genie people, I would HIGHLY recommend getting a piezo lighter, per the manufacterers suggestion. The rare-earth metals (flint and such) that spray out of a bic when you light it over the VG, all end up trapped in that ceramic filter. This crap is TERRIBLE for you, and will collect and collect in that filter over time. Please remember to use a piezo lighter, or be mindful enough hold the bic a decent distance from the VG when sparking it. Here is the data from the VG site regarding the dangers of REM:
We recommend using an electronic ignition (piezoelectric) lighter (or the Ital Hempwick lighter) instead of a conventional flint lighter. Flint lighters produce flint dust, which is visible when a flint lighter is ignited. This flint dust contains "misch metal", which is an alloy of rare earth metals (neodymium, samarium, cerium, lanthanum etc). Rare earth metals are known to be toxic. Hence, we think that inhalation of flint dust should be avoided. And the best way to avoid flint dust is to use an electronic ignition lighter. Please note that the issue of rare earth dust inhalation is not specific to the VaporGenie. Anyone using a flint lighter to light a cigarette or smoke a pipe is inhaling rare earth dust. Any smoker concerned about their health should use an electronic ignition lighter. Below is an abstract describing the toxic effect of rare earth metals on lung tissue. Not good. They are slightly less toxic than cadmium to lung tissue.
Cytotoxicity of the rare earth metals cerium, lanthanum, and neodymium in vitro: comparisons with cadmium in a pulmonary macrophage primary culture system.

Environ-Res. 1987 Jun; 43(1): 142-56
The rare earth metals cerium, lanthanum, and neodymium each were evaluated in an in vitro cytotoxicity assay system using adult, male Sprague-Dawley rat pulmonary alveolar macrophages. Both the soluble chloride form of these metals and their insoluble metal oxides were studied. For comparison purposes, the cytotoxicities of cadmium chloride and cadmium oxide were also quantified in this test system. In general, regardless of the cytotoxicity parameter measured, i.e., cell viability, lysosomal enzyme leakage, or changes in cell surface morphology, cadmium was more toxic to these cells than were the rare earth metals. Of the rare earth metals studied, lanthanum chloride (lethal concentration LC50 = 52 microM), cerium chloride (LC50 = 29 microM), and neodymium oxide (LC50 = 101 microM) displayed significant cytotoxicity in this test system. Cadmium chloride exhibited an LC50 value of 28 microM, and cadmium oxide 15 microM. These findings suggest that rare earth metal fumes should be considered as cytotoxic to lung tissue and therefore potentially fibrogenic.
Not sure if this was posted before, although I have read this whole thread. Regardless, stay healthy people!!
