As a long time grower I have access to the best, that however means I used to smoke a lot. Now I vaporise. It really works, they say better than smoking. Anyhow enough to know it works well for me. I required a portable, I bought the new IInhale but it stopped working after 2 months. so now I bought the Purple days, which is real strong. check out the you tube pressure tests. This is not spam, simply a disappointed user who would like to warn others and recomend/receive good vaps. So anyone got their favourites?
