Heartland Vapes has their 0.5 Oz. brown dropper bottles on clearance for like 50c. I ordered ~50 of them but the first two I have used have both had the same failure. Basically the dropper portion isn't well designed/made and either comes apart or unscrews in your pocket. The top doesn't screw on tight without forcing the dropper to pop apart. Just wanted to warn anyone who was thinking about ordering some. Having a bottle come apart in your pocket and pour ejuice all over your clothes/belongings is not fun.
