I also started with Smokeless Image. Excellent company and excellent products. A great thing to know is that all of their products are compatible with each other, so if you feel like experimenting with a CE3, clearomizer, or a longer lasting battery like the X2, you know ahead of time that it will work.
Be sure to visit the Smokeless Image forums here in the Vendor Forums. There are demo and instructional videos, and the people there are customers who can explain about products and give advice about vaping.
Congrats.
