I "vapor" for some time now .... I got the Joytech Ego One XL'm extremely happy the thing to top it off was always the transport! I tested several options but for e-cigarettes, this variant is really perfect! Is closed narrower than a pack of cigarettes and only slightly larger! A bottle Liquide and the respective E-Zigarrette fits into super! (Does not have to be from Joytech!) * Is not complicated .. Easy to carry in the pocket or wherever! Very well made and delivered super fast! Strong buy recommendation !!!
