I only have the kinds that look like cigarettes, and I doubt too many people notice the difference. I'm the kind of person who wants to keep a low profile, so the little ones are all I've tried. I'm also not into DIY, though I have tried mixing 2 ready-made flavors with OK results. It's nice that others are interested. I hope you make some converts.
They tease me at work becuz my battery is purple, I have this thing with everything matching so they tell me i am going to have to get one to match every outfit!!!! Ya right, let me find that money hole I have in the backyard, lol
