I first bought a pen to smoke herb - the pen said you could smoke herb in it. But when it arrived, I found it difficult to use. I called VaporWarehouse & described my problem. I was told that if I wanted to smoke ONLY herb, the Magic Flight was for me. I sent the pen back & before they received it, I was shipped a Magic Flight - great service!!
This is a terrific vape. It takes a little learning to use it properly. I haven't read all of the other reviews, so if I repeat what others have said, I apologize for wasting your time.
The technique I'm now using seems foolproof. Load the Magic Flight "trench" with finely ground herb. Push in the battery (or push the button on the AC adapter - which I also love!) & wait for some vapor to appear on the plastic cover. As soon as it appears, place the glass tube in your mouth & pull VERY SLOWLY - the slower the better. If it starts to get hot in your mouth, pull faster.
To really get a good hit, after a few seconds of pulling in the vapor, stop pulling (by putting your tongue over the end of the glass tube - that's what I do). Wait again until you see vapor forming on the plastic cover. This time you can pull a little faster, because you have the vape heated up well at this point.
During this entire process, don't stop pushing the battery in (or holding the button in). Control the heat inside the vape by regulating your pull speed - if it's hot, pull faster - if you don't feel any heat, pull a little slower.
Don't expect to exhale a lot of vapor. If you do it really right, the vapor will be absorbed by your lungs and almost none will be exhaled.
That's my method - works great for me! I just bought a second Magic Flight (with the AC adapter & car adapter) & I'm giving it to my son. You reduce the amount of herb used & your high is better than ever. Just a terrific device & a wonderful company to work with!
