I have recently ordered/received my ego and love it. I ordered a drip tip with it and really dig it, except when driving, so I found a cheap solution I'd like to share. Since my other vaporizer is a "medical" device, I tend to have some eyedrops laying around the house. I got to thinking-"this 30ml glass bottle and dropper look cool, but it's not very practical to carry and refill with. So what I did was grab an almost empty visine bottle(8ml size), washed it thoroughly, and filled it up with juice. Now, I can take a whole day+ supply, which fits in my pocket, discretely, and the drop size is a lot more predictable and only comes out 1 at a time.
