The supreme is supposed to work that way although I've never used mine. I'm ok with butane torches but that requires a very large torch- too intimidated to use. And the newvape which I also haven't tried is very popular for strong single doses and I'm sure someone will recommend it.
I had more trouble with the Solo than my current vapes which are all on-demand. I use them with a combination of a whip and bubbler and sometimes just the whip and that helps me a lot with dryness. I wouldn't call them single hit vapes though. I tend to vape on low heat or, regardless of whether I use a whip/bubbler I will cough quite a bit which causes throat problems. My main portable vapes are tubo, MVT, milaana, vapcap. I've slowly been getting rid of the other vapes I've owned like the arizers.
