This probably sounds silly, but where do people keep their e-cig to keep it handy without losing it? I always kept my tobacco cig pack in my pocket or purse when out and on the coffee table when home. I got KR808D-1 regular and XL batteries. I keep putting it down and losing track of it or it rolls off the table. I feel funny just sticking it in my pocket or purse. Is that safe to do? Are they at all fragile/breakable? Should you put the plastic end cap back on when not in use? Should I just wash out my ashtray and rest it in there? I find myself almost constantly vaping these first few days, so I don't want it to far from hand. Thanks.
