I just got back from a 3 day vacation. I took my Grand. I have to say it cut down alot on what I felt I had to take. I had a LR atty on the Grand, and a full 6ml bottle. I took my Pila charger, two extra 18650 batteries, 10ml of juice, another atty, and a cartomizer. This was so much less than when I went to Tennessee in February, my supplies themselves were a small suitcase. I never worried about my Grand failing. We went to a watermark, and I wasn't worried about it getting wet. So my vacation was great, thanks to my Reo.
