Well the freshmint does its work. I mean its as good for cleaning your mouth and removing bad breath as other Colgate mouthwashes.
Prior to Listerine I was using colgate Peroxyl and honestly I don't find one of them to be more effective than other.
Listerine like other mouthwashes works just fine.which means it is able to remove stale/bad breath for two or three hours approx. given that you have not eaten anything greasy in between.( or so I think it is in my case. Never dared/bothered to smell other's bad breath and ask about their oral hygiene )
I guess my only complaint is the strong , irritating aftertaste you get on holding the liquid for 30 sec in your mouth as bottle suggests.
It made my eyes tear up on first application.
If you are kind of man who particulary enjoy that sensation go for it otherwise opt for -
colgate
Listering Soft Mint
Listerine Originals
As I did
