Finally received stock of EM901's for release. These are DY's latest which I now dub, the VaporViper due to it sucking up the juice via highly modified/shorter atomizer. This is a dripping machine. The cartridge is new, and hold twice the juice, which is a must, due the the (viper)hissing of this atomizing monster. The battery is a female, unlike standard DSE, 4075, models. She like to be caressed, and puffed gently, and long. I have found the new carts need to be topped off often, but, not as often as the DSE. I have also discovered there is a perfect match for the Dura/510 cartridge as well. I like this, as I own most all available personnal vaporizers made. The batteries last about 15% longer than the standard DSE/4075 models, I believe due to the shorter atomizer/longer battery. I have these available in both: Silver, and Electric Blue......both with bright red led's You can choose to have 2 silver, 2 electric, 1 of each. Yes, 2 atomizers, 2 batteries, 1 charger, 5 carts.
