Both of my Blu batteries died within a month of use, I then switched over to eGo batteries, Then I went to a Vamo3 with a recharger kit. Then I got an SVD ( very happy with this one).
Skip the middle step, get the SVD (style) unit along with 18650 2400mAh or higher batteries (at least 2) and a NiteCore IntelliCharger. If you are "serious" about vaping, you will end up with this type of equipment anyway
