The Fusions will not disappoint. My husband who would not try anything other than the Smokestik cartos we started with a year ago has now converted to one of my GLVs because he said the Fusion cartos were so much better. He vapes less than I do, and his has lasted him a month now. I
vape 3.7v until the carto gets tight, and then I move it to 5v before I toss it. They last me between two &
three weeks on average.
