Well I gave the PD a shot. Just like I figured they were gone before my page said they were for sale. Not going to wait for a chance to get one. I want to get my first vape!!!! The only reason I mentioned that (well I'm bummed of course ) was because my main reason for getting a vape was for conserving my weed. I went to my local head shops and they carry, well shit. And the volcano. Being impatient I made one at home. I have to say I may never "smoke" again. The flavor is great, the high is F'N AMAZING. The one I made is manual, I supply heat with lighter or candle. My budget is tight right now so I may opt for a vapor genie if the DBV is not what I'm looking for. Enough babble. I had looked at the DBV and I like the temp control, look and price as well. From the pictures I have seen the whip end seems to have a rather large area (width of opening), for loading your bud into. Do smaller amounts work? It just seems as if you need to cover the screen well enough to have the hot air draw over it. Wouldn't smaller amounts just fall down on the glass edge of the bowl, not allowing air to move over it? sorry that's a lot of crap for a couple of questions Be gentle it's my first time. I've have only seen some of the different whips at the local stores.
