So I'm new to vaping, and I got a eGo One about 2 weeks ago. I'm still on my first 15ml bottle I got from the store I got it from, but I'm getting sick of the taste. So I found Mt. Baker Vapor and saw that it was really cheap, and I could customize the VG/PG content. So I just ordered 3 different 15ml flavors. I got Ecto Cooler, Demon Energy, and Hawk Sauce. I watched a video and it said that some liquids can melt or ruin tanks, and that worries me a little bit since Mt. Baker Vapor is really cheap stuff, I'm not sure if it's good or not. But have any of you had bad experiences with certain ejuices? I head citrus can be harmful, but that kinda sucks because that's the flavors that I feel like I'll like the most. Any thoughts on this?
