Hello all, first post here. I'm currently using an Apollo Twist with a BO-8 Triton rebuildable with SS mesh, and an eGo Twist with a Siren ego-t rebuildable, also with SS mesh. I've been thinking about getting either a box or tube mod to get away from the disposable batteries, and was curious about the Innokin MVP. Is it worth the price since it doesn't have a replaceable battery?
