Ive tried most of these Colgate Plax Mouth rinses over the years and I enjoy the fresh taste left in my mouth after using them - especially the peppermint one. The 500ml bottle last ages when using daily.
I think if you are using mouth washes to disguise bad breath consider booking into a dentist or have a health check as it could be something more severe going on in your body. If its only to have a fresh mouth feel and kill some germs then no harm adding these to your routine. Its almost like the a finishing spray on your makeup - makes you feel like you've completed the task but its not the main product!
This is the mouthwash I always purchase. I find that it is less intense than listerine. It is minty and leaves mouth fresh.
