I have been keeping up with FC for a few months, trying to stay informed about the emerging products available in the portable vaporization market. I've been an ardent supporter of the Volcano product line for wired home usage for as long as they've been available, but as we all know things are rapidly evolving in the portable area.
I am personally more inclined towards self-contained concentrate oriented devices for portable usage, but that's not really a fair comparison here. If I were to contrast my experiences with strictly flower oriented hand-held products things become a little more clear; this includes ioLite, nO2, etc. Basically anything that is not "automatic" or requires some type of physical manipulation during consumption, even if that is simply handling or positioning the unit.
In the interest of full disclosure, I had the pleasure of meeting the Hammer team after the last CHAMPS event and they were kind enough to offer a hands on demonstration of the product. A slight aside, they are a couple of nice cats and genuinely fanatical about their product, which I found to be absolutely refreshing
Initially my first impression was efficiency. The degree of control is maintained through three parameters: the temperature of the air path, the speed at which the air is traveling, and the density with which the draw tube has been packed.
Basically how long you've been heating the exchanger, how hard you draw and how well that hot air is moving across the product. There is definitely a learning curve and I certainly combusted the front half of my first load after getting a little excited - holding the torch button down after I had already pre-heated it - while I was dragging too hard for the second or third time
Once I got over the short learning curve I found it to be not only supremely efficient but a physically familiar way to utilize a very small amount of flower on an individual basis. As others have said it is very similar in concept to the experience of a standard "hitter" with a small pack in the end, although much more refined and smooth due to the finer temperature control. Using the product feels very traditional in the sense that you are manipulating the positions and intersections of the pack/draw stem and the heat source with independence.
I personally do not perceive these features intersecting well with concerns about stealth. It exhibits the audible cues of a butane torch, physically the format reproduces a familiar cue of consumption and the loading/unloading of small ground amounts leads me to see it fitting in best at home, or as others have said on a camping trip of sorts.
Looking forward to reading more testimonials in the future as I feel it is both well designed and unique enough to earn a place in the market.
