One thing most here are hard core against is furthering the Financial success of the Tobacco companies at the expense of persons Health and welfare.
Unfortunately the Tobacco companies have realized we are taking a stand and have once again found a way to cash in. They all have or are working to release their own version of e-cig.
Big Tobacco is also lobbying hard to have all but THEIR form of e-cig(disposable) Banned.
Most of Us have moved past the Grasp and have no intention of ever again supporting Big tobacco in any form.
After a bit if reading and internet search, you will come to find many setups the not only rival but Far exceed the Disposable.
I started one step up from you. Never had the disposable. Just didn't make since to me to add to the Waste chain and repurchase at the high cost. I got the cig-a-like kits M401 then a 510 kit. Both rechargeable with replaceable flavor cartridges. Both paid for themselves in that they ran about $60 and I spent that on a Carton of Smokes. Each lasted about the equivalent of 2 cartons before I moved on to something that actually worked and controlled my need for Nicotine.
Never look at you purchase as Costing you. In the end, It is saving you(in many ways)
Personally This became a hobby and in the past year I have collected about $2k in gear and a few hundred in Flavors
Difference is - BUTTS go in the Garbage - Gear is still here

 so I do not feel I am throwing money away and I have things I can continue to use and explore.
Okay, enough for now. Don't want to scare you away.
