@Alan stems are half the vape. Change the stem, basically change the vape. I'm so freaking busy building vapes, and I don't really play with different tubes much. I'm always after the best experience with the vape and stem that will arrive at your door. The rest is up to you.
Well, with the best possible experience in mind, for all possible users, the DNA chip had to happen. It has generated more interest than even the first units shipping. I am looking forward to figuring out this bad boy, and really can't comment too much until I have one in my hands. I've pre-sold a few already, as this is funding the project going forward, and they are rapidly filling up batch 8 which only has 2 spots left. I'm calling batch 8 at 12 - 10 sold.
I purchased 2 chips, and shipping is really fast, so once 7 is out the door, I'll be working on this project as part of batch 8. Alan had suggested this a long time ago, and by removing the front vent hole, he pointed out I made room for it to be installed. He then sent me a link to the chip. Today I clicked the link and thought to myself, I can do that. Not sure if he knows I've opened it up to a pre-sale, but he'll find out soon enough. I have no idea of what the final price will be, but the boards are almost $80 with shipping. I didn't want to plop down hundreds on a chip that wasn't ideal, but if Alan recommended it, I bet it's right for LB.
