I am new to e-cigs and am very anxious to try them. I actually was given a Gaumci, not sure if I spelled that right, it is a disposable and I am not impressed. I order the Duo Pro from ElectronicigarettesInc and I am hoping it is not as disappointing as the disposable. It is a two piece with disposable cartridge/atomizer. Has anyone used this brand and what is your experience.
