(Oh, I should add a few details: the eGo Ones come in various sizes and versions. I have a eGo One Mega V1, and three eGo One Mega V2s. These have a 4ml capacity. The Amor has a 2.5 ml capacity. Coming in the post are some smaller eGo One V1 tanks at 2.5 and 1.8 ml capacity. I use the 1 ohm CLR coils, and the cheapest source I've found for them is Fasttech,
here. Also,
here's a pretty good video about rebuilding the CLR coils.)
