Cash, I'm on my second day with my new mini. I'm just tickled pink (sorry) with the pink color and and pink light. I've strictly been smokin' pen styles for 3 months and there is indeed a difference. I'm beginning to get used to holding it in a different way. At first, my finger seemed to always plug the little hole on the side of the atomizer. It's a bit noisy, but I can easily live with the little bit of noise it makes. The cartridge is smaller, so I have to top it off more often and also, the battery doesn't seem to last as long as the pen styles. I've always been fascinated with miniature things, and this little pink beauty is something I'm so happy to have. Thank you for making this available to us and for donating proceeds to breast cancer research. I think my preference performance-wise is the pen style though because the ones I have are silent and last longer. This little pink one though, is the purdiest one I have and it's vapor production is amazing! I hope you'll be able to have more colors in the pen style soon.
