Earlier today, I refilled my Taifun GS today with the same liquid, Red Bull, that was in it yesterday. It's a nice juice, some what fruity and the Taifun is an awesome atomizer. I started vaping it and I get the smell of fresh cut onions. I'm thinking, well maybe my wife is just made a salad and went up to her office. So I ask her and she says no. I set it to the side and fill up my SQuape with the exact same bottle. It vapes just fine, tastes great. 3 hours later, I finish off the SQuape and switched over to the Taifun GS again, Fire it up and get fresh cut onions. The taste isn't "oniony" but it not Red Bull either. The smell is definitely fresh cut onions. This is a first. Turns out I had a Vapergeist. Washed the coil and wick, dumped the fluid and filled it up from the same bottle. No more onions.
