I have been wanting to try this I have coupons I received in mail to get one free and free cartridges too, but idk where to get them so I thought I would get one here. How does it work exactly? I see it has the like USB thing so was wondering it's purpose. Thanks! Watching fanned and bidding!!
you drag cig it comes with it together when it does not work anymore you try another filter you twist it off. if it works old filter is junk if it still does not work battery needs to be charged and both filters are good. Nice and simple to use..
