Works Well, Tastes Good, Lasts a Long Time
Size: 3 Ounce (Pack of 1)
Needed to get a product with no fluoride and not made by one of the large mfgrs of toothpaste. I used to used HELLO, but they were bought out by Colgate. Not a fan. So, I thought I'd try this as I used to live near the area this is produced. It is a lesser sweet taste than the HELLO product lines, but very nice results after just a couple uses and the taste is fine. Works well, tastes good, affordable.

Keeps breath fresh for longer.
Size: 3 Ounce (Pack of 1)
Love this toothpaste. It’s like another brand that made the pm toothpaste that was good for morning breath. I wake up and still can somewhat taste the freshness. Maybe the peppermint is good/strong, but works well without the burning sensation.

Cleaner teeth
Size: 5.5 Ounce (Pack of 1)
I feel like my teeth get cleaned better with this product than usual mass market brands. Only downside is it doesn't have enough mint flavor to act as a breath freshener. But it's perfect if you can't tolerate a strong mint taste.

Good product
Size: 3 Ounce (Pack of 1)
Seems like a good product. Taste is not bad and texture is good. I have used it for a month and have no major complaints.
