I just got the new K1 glassomizer in along with some of the new Aspire BVC coils. The tank is built nicely and the airflow draw is good (about the same as the other clearomizers IMO). I really like the way it looks on the CF VV+ and the battery is not top heavy at all compared to when the Nautilus Mini is attached. The coil checked out at exactly at 1.8 ohms with juice in it.
Vapor production and flavor is excellent, but still not a Nautilus (adjustable airflow is king). This is definately a must have for on the go. I had the coils out on the close up, I had just washed the tanks out. I will have to get better pictures when I get the digital camera back from the wife. All in all, Aspire did a great job of developing and manufacturing a very high quality small clearomizer that is far superior to all of the old ones. :)
The glass on the K1 in this photo isn't clear because I had just washed it out.
This last photo is the new Aspire BVC next to a Nautilus BVC.
