So I am vaping my mpt3 for the first day. Vape is great. No leaking, lots of vapour and good throat hit. Buuut, I also bought a pack of extra coils. Now I notice these are different than the one that was fitted. On the fitted one the wick sticks out but on the replacement coils its completely inside. Why is this the case. Surely the factory fitted and replacement coils are meant to be the same. This is the box for the replacements
