ultimate =
- all glass air/vapor path
- PID temperature control
- battery power
i just say no to butane
-As I said, I'm sure there are even better materials than glass, and something so fragile can't possibly be ultimate. I love glass, but for example jsut from the top of my head - the minivap used teflon, wchich has very strong bods, so it can stand very high temps without fuming and its not fragile.
-PID is great, but I'm sure it's not the ultimate even today. If price was no concern, you could probabyl get even better results from some simple neural network.
-Current batteries are very archaic compared to the rest of our technology, we are in dire need for a revolutionary battery technology upgrade (and there are lots of them almost ready). Think ybout abattery that can't blow up, changes in seconds, hold charge for a long time, and possibly even weight almost nothing and be thin like paper. That would render any "ultimate" battery-powered vape designed today very obsolete.
-What's wrong with butane-powered vapes? I'm usre a butnae vape couln't be the ultiamte one, but they're not bad. AFAIK, butane burns into carbon dioxide and water and some butane vapes are great, designed to be safe and have the butane and exhaust isolated from the airpath. I also prefer battery powered vapes over butane ones, but can't deny that at least until the battery revolution comes, butane beats batteries in the "power storage" (bring a small can with you taht lasts for weeks) and "recharge speed" (a refill takes seconds). Until super-batteries come to market, butn ae vapes still have something special to offer.
