Decent producut with few drawbacks
Flavor Name: Tangerine Tango, Size: 30 Count (Pack of 2)
Ordered this product for the first time during Prime Day when it was on discount. I can only speak to the Tangerine Tango flavor. Pros: - Comes in a cute little tin as opposed to a plastic bag - Easy to carry around - Good value if you can get it on discount Cons: - Flavor is very subtle - Dissolves fairly quickly - Can experience some moisture issues if left in a warm/hot place - Uses "natural flavoring" Overall, it's a decent product but I'll be sticking to the gums.

Terrible.
Flavor Name: Tangerine Tango, Size: 65 Count (Pack of 3)
I can't speak to the other flavors, but the tangerine is nasty. It reminds me of some really bad bone broth I had, and I don't know why that would I love be in these mints. I love PUR gum, but these mints are terrible.

Watermelon flavored gum
Flavor Name: Watermelon, Size: 50 Count (Pack of 1)
I love anything watermelon. This one is very tasty, I have bought this one several times now. I like it that it is using Xylitol and Erythritol, no Aspartame and the sugar won't affect any user's glucose and cause insulin problems. On top of that it is also using palm tree sap. It isn't hard to chew, it is just right, I can chew them for a long while working on slimming my face. I just hate the type of gum with xylitol to fall apart while I am chewing it.

Unexpected treat!!
Flavor Name: Watermelon, Size: 150 Count (Pack of 1)
This gum tastes absolutely amazing. And doesn't leave that nasty gritty film on your teeth that you expect from most gums. It was a real unexpected treat.
