I guess it depends on what atomiser you prefer. Looks to me like a basic 3.7v
mod for a DSE-901. So, without an adapter, that's what you get. The storm there looks like a better choice there... you have a choice of voltages on that one and the option of a 510 atty. And 60 bucks for a what's basically a modified flashlight? Personally, for that chunk of change, I'd buy something else, like an ego or something, which is built to be a PV from the start. You could quite easily make your own comparable flashlight
mod for a lot less.
