this is just the first copy, to make sure it would fit and i liked it. my next copy will have all 3 matching buttons but i broke one and didnt have a spare, and it will most likely have its buttons on the side so it will lay down flat, it uses an ego connector so i can use my evod. As far as i know im the first to put a dna 20 in this case. the case is the exact same size as an altoids gum container, and i have a pic with a 9 volt box and a normal altoids for size comparison. have to say this is a winner for me, others looking for an small easy metal 18650 dna 20 build it dont get too much smaller at least using an off the shelf enclosure
