Been vapeing over 3 1/2 years and pretty much stay with standard carts, batteries and pass-thru's. Decided on a change the other day and got an EGO (great bit of kit), but now sold out along with the dual coil monster carts. Have been looking at the smileomizers and wonder if they will fit the EGO battery. If I opt to go with a Zeus will the dual coil cart fit that? Want to keep my stuff as interchangeble as possible. Hope you get the EGO stuff in soon. Thx
