It's difficult to run around with a rebuildable on a full length mod in your pocket at work. It leaks if on it's side and is just too impractical I find, especially when you dont have a desk job. That's my dilemma anyway. I'm forced to resort to a Vivi on a short VAMO (18350). Not pretty I know but fits in my pocket and lasts nearly all day.
