Sup guys, looking to buy my first mechanical mod. I know about rebuilding and ohms law but I have no idea about mech mods themselves besides the batteries you put in. Essentially its just a metal tube with a connector so whats the real difference in these besides the engravings? I read a lot of people preferring the nemesis but why? I would like something that hits nice, also wanted tbe black look but only the stingray has it. Can someone please enlighten me on this topic. Thanks!
