A friend tried my first eGo set-up and liked it. I didn't see her for awhile, but the next time I did she said she bought a Blu and hadn't smoked in over a month! I brought over a more advanced kit, so of course she was amazed. I lent her some gear, including 2 batteries and my back-up charger. I told at the time that I would want them back. She doesn't have much money, but neither do I. What does Ms. Manners say is the amount of time that should pass before it is polite to ask for my gear back?
