I have spent 600+ dollars on Vapexhale, the firefly, the volcano and the Solo. This device HITS HARDER, more efficient, almost indestructible, easier to use and clean, and is much much cheaper. Worth every penny. I have used my Dynavap for years and I don’t even look at other vaporizer. I at least 5 hits every time I load it. NOT one or two like in the description! And it very very easy to use. The only thing you have to figure out is how you personally like to light it. Torches are great but induction heaters are even better. They’ll do all the work for you! I have gifted friends/coworkers Dynavaps and they are all hooked! So I know it’s not hard for people to figure out. Best thing to have ever hit the industry!
