EVOD Replacement head question.
First let me introduce myself, I just recently started vaping like a month ago so im still new to vaping.
So my current setup is a standard 900 EGO battery purchased from apolloecigs.com with an Kanger EVOD tank. Now from what i've read evod tanks are compatible with pro tank heads. So my question is do I have to physically change anything in the pro tank heads to fit into my evod tank? For example do I have to change the long skinny piece of metal that is attached to the pro tank and switch it with my old evod heads in order for the head to fit into the tank? And is their any noticeable difference from using different heads?
