Been thinking about this for a while now and finally started to work on it. First prototype is nice, I'm really happy with the look, feel and performance. The big changes are: 1. The touch pad is gone and replaced with a button, internally this eliminates the circuit board and makes assembly easier. 2. The corners have a larger radius so it is more comfortable in the hand. 3. The unit is 1/8" narrower, which isn't much but it is noticeable. 4. The coil is a bit cooler, the abv is golden brown and I didn't combust yet. 5. There is no polarity so the battery can be inserted either way. the button is recessed there it is button rated at over 1,000,000 clicks and the port holes are still here to view the glowing coil. I ran a couple bowls through this one yesterday and I liked it a lot. Hope to get a few of these out to testers next week and we'll let the fun begin.
