I need to break this down into 2 parts first the good. The mesh and regular coils are awesome, 5 stars. They both have great flavor and last a decent amount of time. I highly recommend either the mesh or regular mtl coil.
The ceramic coils however are horrible. They last through about 1 ml of juice before the taste is muted or kinda burnt tasting like a spent coil. The only way I got one too last longer was to let it soak in juice overnight, vape around 1 ml then let it soak again for another day. That coil still only lasted a couple days. A ceramic coil will not realistically last a whole day. 0 star rating on the ceramic.
Mesh and regular, great. Avoid the ceramic.
