So I cannot deny that the flavor you get through the MiniVap is amazing. The Herbie's vapor is much cooler than the minivao, even at 445f. The vapor cools a lot as it travels through the 3ft. whip.
The flavor is also good, but since it's cooled off so much the flavor isnt quite as strong. I do use approximately the same amount whether it be Minivap or Herbie- a heaping smidgen spoonful. The effects from the Herbalizer are longer lasting - it is a noticeable difference. Also, the same dose with Herbie is stronger as well. It's strange because the abv is always lighter with the Herbie. With the Minivap you usually have to milk a bowl for 5-6 hits to get everything. I can plow through the same amount with the Herbie in 2-3 hits, even less if I use the fan and power hit it.
As far as the temps I stay about 390-420, and 445 for concentrates. I have played with lower temps and it is definitely uplifting and a different experience. I am usually not vaping throughout the day so by the time I get to Herbie I want the higher temps.
I don't know how much success you've had using concentrates with the Minivap, but with the Herbie it works very well. I didn't have much success with the minivap.
Bags are great, it's nice to have the option, when friends are over you have 4 bags, so people can have their own bag- very nice.
I should also add, you can irritate your throat with the minivap if you are not careful, where with the Herbie, you almost dont even have to think about it.. high temp, slow pull, fast pull, doesnt matter it will not mess with your throat much at all.
Hope this helps.. Minivap and Herbie make a great pair, no question about that!
