It seems like all 3 types of clearos I use emit a slight metallic taste with the vapor. I've washed them well before using and it is present with all the various juices I vape. Does anyone else taste it? Is this just taste coming off of the nichrome coils and/or metal parts of the clearos that come in contact with the juice? It has a pretty distinct metallic undertone. I notice it more with one note fruity vapes. I think the more complex juices of bakery or tobacco nature do tend to mask it more, but I still pick it up. I wish there was a way to create vapor without heating the juice directly on metal. On a side note, I am very allergic to nickel when in contact with it on my skin, so far I don't think it's bothering me with vaping, but it makes me wonder if it could.
