I haven't noticed any taste to mine. I have noticed they tend to collect more lip goobers on them. lol. Not sure how to describe it. They don't get hot when I am dripping at high voltage but sometimes, depending on the type I am using, they might get a little warm. I have heard people in cold areas don't like to use them during the winter time, but I'm in Florida so I don't have that problem. They do feel cold to your lips though at first.
