Hey vapeman, on the matter of your parents smelling your vaping, it is dependent on the ventilation and relative isolation of your upstairs room to wherever they are. The solo is more or less sealed as the air enters at the bottom of the device and the herb is at the very top, sealed in by the stem. The pax with its oven door as the air intake as well as what keeps the herb contained, makes it significantly smellier than the solo - think solo's aromatherapy bowl but with herb. In my experience, even down the hall, the smell is noticeable if they know what to smell for. Hope this helps, because the pax is a beautiful piece of hardware, but not necessarily the stealthiest.
Also, if you'e with parents, cleaning every week with heavy usage might be a more of a hassle. "Son! Why are there pipe cleaners in the toilet!"
