The Caliburn & Koko both use the same pods, so you wouldn`t expect much differences here if any. While slightly lower in grade for flavour vs the Yearn the Caliburn still produces remarkable flavour with every hit, time after time. Equipped with a 2mL refillable pod from the Caliburn G, the Uwell Caliburn KOKO Prime uses the Caliburn G Coils to produce outstanding vapor and flavor with the 0.8ohm meshed coil and introduces a new 1.0ohm FeCrAl coil for those that are more flavor oriented and love the MTL aspect of vaping.
