I got this a few days ago. Lifting the mouthpiece, which sits loose in its hole (there is a silicone mouthpiece that requires no o-ring but it sits in a separable plastic outer compartment that has no o-ring) a couple of wires are visible through a hole right next to it, that might or might not be effectively separate from the airflow, but in any case the draws smell unclean after several burn-offs and chambers. It gives a big hit when packed, (which I enjoyed optimising using both ends of a 3/16 drive hex socket) and the Auto Puff feature works especially well. It has sharp corners and the plastic lid is not sealed. If this were made of good materials and completely isolating the draw, the performance would justify that or a higher price. But it isn't, and given what X-Max, Arizer, Boundless etc are doing in the budget space Goboof should goback to the drawing board. I will put it back in the draw mainly because of taste/safety questions and better options.
