I've been a smoker for over 20 years - 1/2 to 3/4 pack of Marlboro Light a day. I've been researching as much as I can about e-cig and ECF has been quite informative. I've decided to start out with the V4L Vapor King Starter Kits (VK-Ultimate Ultimatum Kit). However, it seems there are more choices of color for the manual battery than the auto; auto - Copper, Metallic Red, Green, Purple, Gold; Manual= Chrome, Metallic Red, Red, Blue, Gun Metal Platinum, etc.... Are those the only colors for Auto or is it because they're out of stock on the other colors? I am looking for a black auto. I also want to test out both the auto and manual. Does anyone know if they allow you to get one of each on the order, instead of either 2 autos or 2 manuals in the kit? For the juice, what nicotine strength should I buy for a 1/2-3/4 pack a day smoker? Much appreciate for any information. Thank you.
