Sticks uses about 4 times less medicine per month then I do. We kind of talked about it earlier. For me the efficiency is spot on. Anything smaller and I would need to do more then one session... which kind of starts to make the device more annoying to use. I got back from the farmers market. I ended up getting some awesome organic strawberry and rhubarb plants... 2nd year cutting's no less so I will be able to harvest fruit this year! I got about 6 sessions out of a fully charged battery. I probably could have gotten one more, but I wanted to charge it for the show tonight. I feel like this portable will probably become my default. It fits my needs quite well. When I was out today I started at 400F and worked my way up to 415F and finished there. Gives me a little less sedation and a better medicated state for walking around at the farmers market. I love how many needs and usage expectations people have for vaporizers. It just goes to show that what is going to hit every requirement for one person might be not work for another person. I usually monitor my loads in the beginning with a new device. The Ascent is between .27 to .4 (I probably load a little over .3) The PAX is between .3 to .55 The INH004 is between .2 to .3 The Cloud is about .27 to 3.3 I have problems fitting enough herb in the Pinnacle... I tended to pack it tight around .25 or so. I also have problems with the Solo... I tend to pack it full and do about 2-3 stems. So each one is about .15 and I end up doing .3 to .45 a session. For me anything below .2 a session will start to wear off in about 30-45 minutes. After .3 I start getting an hour or more of relief with most portables. It does not extract as well as the cloud, but in terms of my other portables it is up there in the top 2 or 3... like I said still forming my opinions, but I am really impressed. I find I hit the device more like an INH004 or Solo then I do a PAX. I breath with my lungs instead of drawing with your mouth. At this point in time, I like the way you hit the Ascent much more then the PAX. About the size. I have an iPhone 4 with a 12 South Book Book Case: It is a little less wide then the iPhone itself. It is the same thickness and height as my iPhone and BookBook case combined. Fits in my front shirt pocket well. Sticks is right the grill does get warm so the air entering the device gets warmed up some. I don't know if this affects performance at all? After a session I was able to put it back in my first shirt pocket with out any discomfort. It was warm, but not warm enough that it was uncomfortable for me.
