I love my kanger protank v1. The only time it leeks on my is if the fluid get below the 1/3 mark. The only thing I dont like is the metal tip. Looks sharp but gotta be careful driving. I hit a pothole the other day and almost broke a tooth. Might try some aquarium tubing next time a go to the fish store.
What is the deal with dual
coils? Do you get more vapor, hotter vapor, better flavor??
