I started using this toothpaste about 2 weeks ago after repurchasing an Oral B electric toothbrush with a free tube of this included. Initially I was shocked to see a toothpaste that costs R50 but I now think it is worth the expense.
The toothpaste is quite concentrated so despite the size of the tube it does last quite long as you only need a small pea sized amount. My teeth feel cleaner and whiter already.
The only down side is the taste, I find it has a rather bitter after-taste which disappears after a few minutes.
