I managed to purchase this for $2 on an online sale. I have been using it for almost a month now. It tastes different, herbal? it's not a bad thing. It's not a bad taste or a good taste. The gel itself is a murky green colour. I haven't noticed my teeth looking brighter, though my teeth do feel clean after use.
I'm not a huge fan of this, i'll most likely go back to my Redseal toothpaste when this one is finished.
I didn't like this , it was expensive and didn't taste too great. It went a weird off colour. A no from me.
