You really will notice a difference!!! The initial cost of a rechargeable system is only a bit more but save much more in a short time. The air flow is much better too. The scratchy throat can be part of the problem, but the PG used in the cartridges and liquids can cause a dry throat. Lots of water !! I have been away for a bit and have just a couple places that I use: Veteran vaper, vapor talk store, ecig express all have good starter kits. keep in mind, there are cheaper, but cheaper is not always a good thing. its a matter of, do you want a thin cigarette type or a slightly larger battery (charge time last longer)?
