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.
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'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 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.
