Well, I finally had a chance to light up my own tester of Coconut Bubble this morning (been testing other scents and didn't want them competing), and I can safely say the "no throw" is definitely a problem on my neighbor's end. It's been burning for two hours and I can smell it everywhere except the rooms that have doors shut. It *is* a fairly light scent so I think it's being drowned out by her plug-in scent, and I'm sure her burning it in a closed-up room was part of the problem as well. I guess this means no more testers for the neighbor! :lipsrseal
