Are coils from different manufacturers interchangeable? In product descriptions they all say a specific device name on them. But then in reviews of mods you often hear things like "It's not the best coil available . . ." as if you had a choice.
If coils can be swapped out between devices, what are the key specs? Resistance in ohms? Are the threads the same?
