Qualitatively perfect, contrary to expressed concerns and problems with the Nautilus-glass tanks, I must say that you have to dress with the feeling parts. Once the glass tank seals on the moistened with a drop Liquid seal, it takes no more Tighten powerfully. Tightness is perfect. No signs of any manufacturing defects.
With the 2ml tank is evaporated easily spend a day through (as a "normal" ex-smoker), the battery will last longer than a day by.
Comparisons to other manufacturers I can not give, because this will be my first and probably the only device, as sublime in every way perfectly and doubt. You could treat yourself to a second Nautilus to be only in order to avoid "the hassle" refilling if you want to insert a different flavor in the short term.
The device is delivered in a high-quality packaging. Also nice is a multi-lingual illustrated instructions.
Not to mention, the 5 replacement evaporator heads. Thus, one has already some time resting, only the liquids are to be feared.
My recommendation: take your time, go into a store and try Liquid. With a 15ml vial Premium Liquid to 8 euros to get normally from one week.
Seen Unter'm line: Clear recommendation, just because of the AirFlow Control and the controllable battery, because this is often but already practically when the respective Liquid's can adapt to his personal draft and intensity.
