I have a Tobh V2 18650 and 26650, Grand Vapor Trident V2, Igo W, Nimbus and a tiney little Smoke dripper. The Grand Vapor screws broke the nimbus requires a very small allen wrench to rebuild which I will loose eventually. I find myself grabbing the Tobh 18650 most of the time the large 5 post 26650 Tobh is overkill.
