I'm going way back with this one. This is the FIRST vaping product I ever bought. If I'm not mistaken, Kik Sticks doesn't even make these e-cigs anymore... but what they hell, I'll still throw up this quick review.
The coolest thing about this product was the fact that it came in what looks like a cigarette pack. In terms of helping people quick smoking, having that cigarette pack can make it seem a bit more realistic. Plus, it's easy to travel with.
The pen wasn't super heavy, again a nice thing for someone using it to try and quit smoking. Some of the other e-cig's I've tried have been extremely heavy for being so small, and that's a bit of a turn off.
Battery life was pretty good on these, would usually go a day or two. Biggest problem was airflow. You weren't really able to take a good long rip, so you never got very big puffs. You were still able to get a bit of a nicotine buzz though.
While I don't think I will ever buy another e-cig style vape pen, I do keep this product in my car as a 'back up'.
