Most new people when they first buy a kit want anything that looks and feel like a cig because they just don't know any better. When I first started I had never even heard of a mah let alone had one. There is a big learning curve and I believe that the average person has no idea about electronics. The kit from my vapor store gives a couple options for top/bottom coil at a relatively good price. It has a good battery life which is very important although you don't know that to begin with. The people who have decided to try this want it yesterday. There are better prices out there but someone who is new to this just gets frustrated and irate when equip doesn't work and might give up. At least for the first kit they have a basic warranty from a us supplier such as it is.
