I bought the No 7 Disposable for about $14.00 with shipping just to try out an e-cig. I just could not see slapping down $70 for the nJoy nPro kit I saw at the corner store without trying them first.
Shipping was fast and it came with 4 cartridges, an atomizer, and a non-rechargeable battery in a cigarette box. Oh, and a 10% coupon code "NO7UPGRADE".
The battery got me through two carts smoked over two days before the battery ran out mid puff. But over those two days my two pack a day habitat turned in to 1/2 pack the first day and only 3 Camels smoked the second. Even better, my wife freaked out that I was smoking in the house until I blew a BIG hit of vapor at her. "Vaping" is now approved by the house boss, no more back yard for me! Except that now the battery is dead and I have to order a starter kit.
I'm going for the M401 kit from litecigusa.net that comes with three batteries.
