Wow! Slow down. I'm new here but in the spirit of trying to pay back a bit for the excellent advice I got from this site by reading other folks posts the following is an attempt to give my understanding of what's going on based on my (modest) experiences as well:
"Another thing that bothers me is that you cant load small ?"
No. The recommended minimum is half a gram, I suspect nothing less than about .2 grams will feed.
" Why not loading a dab of oil ? "
You need to fill the first chamber well enough so the that end of the wick gets soaked in (melted) oil so it can 'wick' into the second chamber for the second heater to vaporize it for your pleasure.
"Is this what the nail catrige is going to be? "
Probably.
"Some guys say it is better to load a whole gram than half.. Because it sticks to the walls ? Well does it stays there or get eventually vaped after some use or it just stays there till the cart is dead or cleaned ?"
Many related issues, no simple answer. You need to get the oil deep enough into the cart to reach the first heater so it can get heated and fed to the second heater. If the oil sticks higher up......it sticks higher up. Some will flow down on their own over time (like the one I'm using, and Pure Gold), some need some help. Once they get there, heat from the first heater should keep them feeding, but they need to make physical contact. Some will remain even after vapor stops, THC estimated 10 to 20% of the initial fill if you try to heat and dump it out. There is no way clean it out. Dirty oil will eventually foul the cart for this reason.
Eventually, the heater itself will fail (no doubt without warning), just like light bulbs burn out. Like light bulbs, some will die 'right off' (hopefully very few), most will live 'average' lifespans (a few grams worth), others might be record setters. While, like light bulbs, you can kill one early through abuse (like running dry) you can't tell which will be the lifespan winner out of the box.
"Can you finish 0,5 g with a single charge ? "
No, not in my experience. It took me two or three charges to go through that much Pure Gold.
"Is there a waste of oil ? Is it more efficient than the eclipse ?"
I think so. A gram gives you 200 or so doses......how many from your eclipse? I burn 50 to 100 mg a shot in mine so that gram is good for a few dozen doses there.
"Does it kills the taste on the first hits because aroma oils vape lower temp than thc and other stuff ?
Wouldn't that be a loss of taste ? If i load a whole gram and the taste is gone after the first sessions ?"
No. Fresh oil is constantly fed from the first to second chamber for use. Each hit starts out from basically the same conditions. It's neat. You really do load it up and hit it for weeks. Or days depending?
"I vape oil mainly because it gives me a more strong and concentrated taste than bud . How is the concentrate's taste vaporized from the omicron compared to taste of regular herb vapor ?"
It depends on the oil. Some taste more than others. But understand, this machine is not designed for recreational use. It's intended to deliver medicine to those of us who need it........
HTH

! Taking an omicron hit for you now
