I am thinking of purchasing a LT from a vendor and have watched a couple of reviews on this device. The one the PBasaurdo(sp) said is that the DCT tank will not work. This worries me a great deal as that is what my wife LOVES to use and hates it any other way. Has the problem been fixed or is there an extension cap or accessory that will allow the device to work? I'm not buying her a LT if her Madvapes DCT tank won't work. I know there are "better" tanks out there but i'm not paying a lot of money for this since its a way for us to save money.
