I've tried restricting the airflow, different kinds of flower, ground, cut, dry, not so dry, and I just don't like the unit. Heat up is slow, battery life sucks, the form factor is terrible, and it just doesn't work for ME.
Maybe it is just me, but I find that vaping is personal, we are all unique, and we change and evolve. I don't like the Tera, I cannot recommend it, but for others, it ticks all the boxes.
For me, I really like my Flowermates. I had to learn how to pack and use them, but they produce way more vapour than any other vape.
The Tera is a convection vape, and I just don't find convection to be the best. Taste is great, leftovers are palatable, but it is like sucking empty air. I switch to convection after I have a buzz, or when I need to get work done.
While I like the Flowermates, they are a pain to load, and clean, and keeping them producing vapor. Improperly packed, or dirty, the Flowermates can be frustrating. The point is that Flowermate works for me, but it might now work for you.
In terms of heavy use, say more than 2grams/day, the Solo II and the aroma tubes are the easiest for me.
