Great mints and great for you!
Flavor Name: Tangerine Tango, Size: 30 Count (Pack of 12)
Wonderful mints! The fact that they do not contain aspartame makes them even better for you! The taste is citrus flavored and not too strong. There is a smooth texture to the mint.

Tangerine is good but not really minty
Flavor Name: Tangerine Tango, Size: 65 Count (Pack of 1)
Good flavor but isn’t minty despite it saying “mints” on the bag. It had a very slight coolness but if you want something that is literally like a true cooling mint, I recommend getting one of the more classically known mint flavors.

My favorite
Flavor Name: Tangerine Tango, Size: 30 Count (Pack of 2)
Great ingredients, great taste that’s not overpowering but still full of flavor. I’m hooked on these and will happily finish a tin in a few hours if I let myself >_<

The best tasting “mints”!
Flavor Name: Tangerine Tango, Size: 30 Count (Pack of 2), Flavor Name: Tangerine Tango, Size: 30 Count (Pack of 2)
These mints taste amazing! I have been looking for something just like this without any type of mint flavor and these do not disappoint. I am trying to kick my jolly ranchers addiction, and these will work for that. I take a medicine that tastes quite nasty, so finding something sugar free that tastes great was really needed. Plus they help with dry mouth, which is a plus. I originally ordered the small 2 pack, but as soon as I popped one in my mouth, I knew I was going to need more, so I have already ordered the bigger package. Do not hesitate to buy these!

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.
