Here's my collection of random notes about the Vapman, my favorite portable. I've had one for over a year now and I'm pretty happy with it. I had the VaporGenie for about a year before that, but it has now been relegated to tobacco use. I've also owned the Vapir Oxygen Mini (which I would NOT recommend due to plastic fumes and a crappy battery pack) and the I-Inhale (which I like!). I also have the semi-portable original Vapir with the battery pack, but I wouldn't recommend this either. About the 3 holes in the mouthpiece: I think they're just to mix in cool air so you don't dry your throat, and so you don't have to pull so slow. Covering them with my fingers does produce a more dense cloud. The usage video on the Vapman site is very helpful, but here's my modification: I count 4 for the first heat blast, pause for 2, then heat for another 4-5 seconds until I see a wisp of vapor from the mouthpiece. This requires the right lighting (looking into darkness with light behind you), and only works for the first pull, but a little practice to get the timing of your particular torch down, and I can now do it by counting if the lighting is not ideal. I use the Prince PT-4000 torch. I think it's made by Blazer and sold under their brand name also. I've had many other torch lighters that all died within a few months, but the Prince is still solid after > 18 months of use. Not cheap, but well worth it. Compared to the II: I've had my I-Inhale for about a week. It seems less efficient than the Vapman. Spent herb is not as brown, and it seems to take a couple minutes of pulling to get the full effect. With one dense pull from the Vapman, I'm ready to go. On the positive side, the II will never burn your material. The II is great, but so far prefer the Vapman by just a bit. Vapman Cons: In its travel pod it's smaller than it looks on the website, but still a bit big/round to go unnoticed in a small pants pocket. It's possible to burn your material until you get the timing down for whatever torch you use.
