Straight wick, optimized postioning of the posts, sizing of wick hole, placement of air intake, all around he tweaked and tried to perfect the design to make it just a quicker simpler process with the best results with the least amount of fiddling, while still being a rebuildable.
Now that is ignoring the magnetic switch which is a guarenteed break of a circuit when you release the button, the venting design around the button. There are numerous manual protection aspects of the PV that honestly Zen~ would best be able to answer, but if you read the ECF rules that are getting posted, you are not getting any of that, but you are getting solutions to the same problems they are pointing out, from an advanced perspective. The magenetic switch invalidates alot of short issues by itself. The venting that the ECF Guidelines are calling for are extremely dangerous, an unobstructed bottom venting system is prefered, of but the button is there, ok well vent around the button......simple clean solutions to problems that many mods overlook.
Ok but granted I bought the Zenesis (I paid I can say that) because of these features and many more, honestly hands down I think the Zenesis will live up to my hopes just based on the engineer of it, and based on numerous peoples reviews it lives up to my hopes and probably excedes them...............
Ok waiting 3 weeks is gonna suck......
