Hi Romann, Welcome to the Forum.

As already stated it's probably your tastebuds. Have you tried using a cartomiser? What's your juice flavour? Do you have any other juice, or just from the same vendor? Did you wash your clearomiser before use?
This could be many things, some people have a sensitivity to metallic tastes, some people swear they can taste metal when using NiChrome coils as opposed to Kanthal and visa-versa.
in my exp with attys not clearomizers there are some coils that are defected ie made in CHINA for cheap that gave me the metal or burnt electronic taste i would recommend a different clearomizer check your warranty also its a good thing to look for a local vendor so you dont have to deal with the dreaded wait normally you can find a backup atomizer for under 20 bucks as a back up for the wait that is if you have a wait
Seriously??
It certainly seems you know an awful Lot about this, can you please tell us who the US manufactures are? Can you also please give us your recommendation for the different clearomiser that has not been manufactured in China? Who charges more than $20 for an Atomiser?
