Okay, my first attempt at a review.
I started with a mall kiosk e-cig and it quickly died on me (after 2 weeks it wasn't working at all). So, I did some research and decided to go with the RN4072, which I bought from www.mypvshop.com I have to say, I love this e-cig! The vapor production is great, the batteries last a good while for me (about 8 hours and I vape a lot throughout the day). There are a lot of customizable options, even a car charger, which is great.
The Penstyle is longer and heavier than the "standard" e-cigs, so it does take some getting used to. I do love the whistle type flat tip - it's awesome!
Essentially, if you don't mind having an e-cig that is heavier and longer than an analog, this is the one for you! Great vapor production, long battery life, easy to use and many options as far as colors, etc. I will suggest that first time buyers get multiples of everything. Get at LEAST 2 atomizers and 2 batteries. A few draw backs - the carrying case they sell does not actually fit the atomizer, so the atomizer falls out of the case whenever I open it. So, be aware of that. And, there is no charging carrying case for this model that I could find, which is something I'd like to have - but I'm not willing to change models just for the pcc.
Finally, the atomizers seem to be semi-sensitive to the juice that you use in it - VG based liquids seem to "gunk up" the atomizer very quickly. So, I have started sticking to minimum 70% pg juices and my atomizers are lasting longer.
All in all, this is a great e-cig and I plan on sticking with it for a good long while. The vapor production is great and the parts are relatively inexpensive.
