I've been using this product for a while now, and I think it's great except for the price. I personally like the feel of it.
I've always been interested in the cute packaging and finally bought it. It's a soft paste with no unpleasant aftertaste and is easy to use. It has a light, refreshing feeling, probably due to the baking soda.
I feel like my teeth have become a little whiter. The mint flavor makes brushing my teeth refreshing.
I try to buy toothpaste with a strong whitening effect in the morning. I don't expect my teeth to get any whiter than they are now, so I use this to maintain the status quo. I like the foaming effect, so I plan to buy it again.
At first, it has the typical mint taste of toothpaste, but as you brush your teeth it quickly becomes tasteless, so it seems like some people like the taste and others don't. I felt refreshed after brushing.
