The Hercules looks awesome but man, that's a steep price tag haha.
Not really. I made the mistake of thinking that way when the Herc first became popular here. Since then, I ended up spending far more than $100 on gadgets that did not meet my needs. I certainly wasted more than $100 of concentrate, burning it on coils or losing it through messy loading.
The yin and the yang of the Hercules is electrical power. Tiny filament wire heating elements (like an incandescent bulb) run real nice at the 9W limit of Ovale Ego clones. The Hercules uses a ceramic rod heating element (like a soldering iron) that runs at 20W to 40W.
I need to stop and talk out loud about where that power goes. The power heats up the heating element, which in turn heats up the concentrate in contact with the heating element, which in turn heats up the concentrate adjacent to the now-hot concentrate. So, if you have a glob of wax, the edge of the glob touching the heating element gets heated. The hot melty wax heats up the wax in the core of the glob... eventually all of it gets vaporized. Well, not all of it; if that heating element is super hot, some oil is going to get toasted.
Think of toasting a slice of bread. The machine has hot filaments on each side of cold bread. Eventually the slice of bread gets really nice and warm, the surfaces of the bread facing the elements get dry, and horizontal grill marks appear on the bread. That is the delicious essence of toast, the toasty marks on them. As long as very little of the bread is charred, the toast tastes fabulous with salted butter. If too much of the bread is charred, the toast will taste like ass. On the other hand, you could heat a cold slice of bread on a hot skillet over the stove. The bread will get hot - very hot if needed - but you're not going to get any grill marks, and your kids will reject it as "not toasty".
Back to getting medicated. A very small, thin, hot coil will ultimately burn concentrate that it is in contact with. A tiny 30g coil will run at 750F, heating and bubbling wax away until the wax sublimates. A bigger, heavier coil (say 28 triple twisted) can run at a lower temperature, yet still deliver as much heat to the wax. But, a bigger heavier coil needs more energy to run. Taking this to the extreme, the Hercules uses a huge heavy ceramic rod instead of tiny filaments. It is not efficient in the sense that it requires a humongous amount of energy to run. But, it can be driven at a relatively low temperature, while delivering all the heat needed to the wax. Wax that is in contact with the hot Hercules rod is alot less likely to burn/char than wax that is in contact with a very hot filament coil. The yin.
The KISS cart is the best filament/coil setup out there for either burning wax or vaping wax. (There is a local firm outright ripping off G's designs, it is the only thing on the market that is comparable.) Yeah, alot of people just lay wax on top of the coil and pull the trigger, leaving their coil crusty at the end of the night. I prime my KISS wick by pulsing the power just enough to warm the coils, then dab it with concentrate, letting the wax melt and flow into the wick without getting hot enough to vape. Then I vape off the wax in the wick - all vapor no smoke. But I know the temptation to drop wax on the coil, because I too was chasing bigger hits. I was abusing those KISS carts until my Herc arrived. The Herc has since paid for itself, as measured by all the concentrate I burned and got on my fingers abusing the KISS.
The yang of the Herc is its power requirements. You can't drive it with a small compact inexpensive battery. The price for entry is a battery/vape that can deliver 20W to 40W. That's alot of power, even for ecig users. You'll also end up with gear that is nowhere as stealthy as an Ophos or Omicron Lite. If you take dabs off the nail before leaving the house, and use the KISS to stay on the level with hits every few hours, you probably will want the Ophos/OmiLite over any million dollar megavape. But if you need a portable daily driver, you're going to want a Persei+Herc. I wish I hadn't wasted a bunch of time, energy, and money trying to improve, improvise, or make do with lesser gear.
Edit: You'll kill an Ophos/OmiLite quick trying to drive a Herc, that is battery abuse. You will get miniscule runtime, and wispy hits. I swear the dude on the video vaping on his OmiLite got lucky, not even G can reproduce it on his office units.
