i already don't like 'em, first off all, they think they have to show a bunch, and i mean a BUNCH of 'hot women' holding their product to sell it, second all, it's the entire wording of the thing, i know it's for legal purposes and all but goddamn, everyone knows that shit is marketed for teens who need an escape from their parents being able to tell, third of all, unless it costs less than 3bucks, it's a rippoff tobegin with, you can get the same effect froma toilet papper roll and a few dryer sheets, fourth of all, the're leaving out one important fact, the smoke that comes off the cigarette ~cough cough joint/sweet~ cough while it's burning, it doesn't make a fuck if you blow your exhaled smoke through some over-zealous device, there's still going to be alot of tell-tale smoke left in the room..... only thing i can really see it working for effectively, is a pipe you can cap, or a bong you can clear 100% and cap...
