If I could only have one vaporizer it would be my Mighty, and it’s because of consistency. On demand convection tech is good, it’s just things have to be a certain way. For my Firefly 2 if you can’t inhale with quite a lot of force for six seconds minimum then don’t bother. For the Ghost you have to be able to inhale for 13 seconds minimum with whatever draw resistance you want or don’t bother. If I didn’t quit smoking I could never have inhaled that long for either vaporizers. First thing in the morning I can’t inhale that long. At the end of the night I like to just set it and forget it as well. For the Ghost the herb has to be fairly dry, it can’t be ground fine, the batteries (at least in my case) have to be topped off before the indicator says, and it has to be clean. It’s not crazy rules, and it’s worth it. Still though, only if I own other vaporizers so I don’t want to worry about that stuff every time I want to vape. I really don’t think it’s the tech at fault. I think people don’t realize the rules for on demand. The review videos don’t lie about the great results, but they are seriously hurting themselves and everyone involved when they make these things come across as perfect results the first time. I will say this though. After you pick up a Ghost every other vaporizer will feel like crap in hand. I hate picking up my Mighty. As great as it is, ergonomically speaking it’s a piece of shit. OSHA would ban them if they were office equipment.
