When I was using the ego batteries I had 4 650 mah batteries and 2 650 mah twist batteires, now I only have the ReoGrand and 4 18650 imr batteries for it. I'm loaded up on atomizers mostly, 2 hh.357, 8 cisco 306 (4 1.4 resist 4 1.8 resist) and have 2 joye 306 and lots of drip tips LOL then I have the various replacement parts just in case, 2 sets of the magnets, 6 bottles, 3 springs, 2 of the delerin buttons, a couple of tubes and orings. I'm set for quite a while, and since the local store sells the juice I use I don't have to stock up on juice.
