Works great for the exhale
Works great for the exhale. Does not have any effect on smoke coming from the source so there will still be a smell, but if you just want to be discreet or polite this is fantastic! I added cotton balls on the mouth end to absorb some of the residue. I remove them and replace them as needed to make the product last longer (I HATE disposable). I have seen ways to clean the unit, but I'm not into that much effort so I just use the cottons. I love mine so much I am giving them as gifts to friends now :)
