Here are the pics, gotta say I am reasonably convinced that the G3 is the same as the Inhalater. There are a couple of minor differences, but that could easily be explained by tweaks in production between the start of the XP to the INH005. Some of the parts got kind of mangled as I pretty much had to tear this apart to get the heating chamber out (mostly due to the indicator light sticking out the side where on the INH005/G3 it is flush).
As you can see it is the 4th unit:
Here is the bottom knob, had to tear this off as the original XPs could not be unscrewed at the bottom:
Here is the heating chamber together, excuse it being a bit crushed:
Heating chamber outer:
Inner heating chamber part once again excuse the oaf like crushing:
You can see the wires going into the heating chamber which are a lot thinner than on the G3. Wouldn't be surprised if the wires on the INH005 are also thicker and this may be why this unit failed so quickly:
Here is some of the tape holding the inner chamber together as well as the screen:
Got tired of trying to untape it and just cut the inner chamber open and it looks basically the same material as the G3:
Only real differences I could see were that the wires going to the heating element were thicker and protected on the G3, and the XP had no tape on the plastic outer heating chamber. Those could be the same if an INH005 were torn down. A bit of the white heating chamber is visible when looking into the XP though I never really thought about it being plastic and certainly didn't think that plastic was encasing the entire heating chamber. I think both the XP and G3 are probably safe, but if stealth isn't your main concern then you might want to go with something else as it probably won't taste that good. Bear in mind that my XP replacement was one of the "too hot" units, so an improved XP or the INH005 might taste great. Though based on my XP experience and with the member or two who have tried the G3 I wouldn't bank on that.
