You're right, it's a neat product. I hope when the Pocketpuffer is released for public sale RFMK will put out a promo-video that will show it in use. I like the 2 chambered idea, I also think if you're going to buy a porta-vape bigger than an E-cig then it should be big enough to be a comfortable fit in your hand and have a lot of battery power; which the Pocketpuffer is more than rumored to offer. The dual chamber idea is an added plus.
We've seen a lot of compression on the RFMK chart this past month and the volume has shrunk to impressively small amounts so I think it's safe to say that the selling has settled and this thing is about ready to make it's next big extension. We'll see what happens this week, RFMK could get interesting, especially if we get a substantial PR.
How could I make such bold presumptions you say? Elementary my dear Watson, I enjoy speculating.
