Unfortunately, that is "working properly" by no means guaranteed. Of the four evaporator heads that we had was a quasi factory defective (assembled wrong, thread damage, hence leaking and Liquid everywhere). The other three work in itself, at least as far as tightness so easily; Curiously, the wheel with which to set the air supply for all three evaporators turn a different resistance at the beginning. During a nearly already turns, if you take an angle look at it from the side (leads to the other is difficult to move, without fear, the thread on the Nautilus or the battery carrier to berschädigen (turning right around screwing rather the Nautilus off completely when the wheel to move without the firm grip on the threads of the battery carrier is an adjustment virtually impossible.
The evaporator heads inside are another matter. Of the total of 8 that we got with the evaporators, were four completely unusable - poor development of steam, charred flavor from the outset, thread "factory" not usable, blocked air supply (can turn suck like a poor madman, hardly occurs what out) - as the full program was really represented to possible defects.
How actually said a nice and good product, but unfortunately the production (I suppose in some low-wage countries) hardly seems to operate quality assurance and the dispersion is very high as regards the evaporator heads inside. Assuming that this is a wearing one must therefore probably heading for a rough doubling of "operating costs", if like us, every second is of no use.
I myself will for now remain the iClear 3 and again enter the Nautilus in 1-2 months a chance in the hope that the quality problems only relate to a larger batch.
