I have experienced numerous amounts of time where the LL core could not physically evenly burn without proper inhaling techniques.
This reminds me very much of the complaints that some have toward the MFLB. Both work amazing if you learn to work with them.
Even with proper use it doesn't have much capabilities of multiple sessions as the ceramic body and core retains heat very easily for a while.
I disagree, it's experienced usage that makes the heat manageable, depending on your usage scenario (number of people using simultaneously).
I agree that a heavily technique dependant vape is probably not the right choice for a first vape. I'd go further than suggesting the Pax and suggest that a flame powered vape like the VG might be better for learning the ins and outs of vaping, as well as being a more cost effective starting place. The Lotus has less of a learning curve than the VG I think but is more expensive, though there is the prospect of a Massdrop sale in the near future.
Another reason to start with a flame vape is that they are always a good compliment to an electric one that you might get later. It's important to have a backup to mission critical equipment!
In my opinion, the Loose Leaf Cera's specialty is powerful convection vaporization in a supremely cleanable body with swappable batteries, top notch flavor, and comfortable high-temperature vapor delivery without using a water tool. It's not the vape for everyone or even most due to some of the drawbacks mentioned above, but if you're someone who highly values each one of those points I mentioned and don't mind manual drive/technique, I don't think there's anything else on the market that can touch it.
Another option perhaps is the original DaVinci vaporizer? They've gotten mighty cheap now and are probably the stealthiest electronic option at that price point. Haven't used one but I think it's worth looking into.
