Ex Input:
I tried this gum after Trident cinnamon became hard to find a couple of years ago. (Trident told me that they were overhauling the plant that made the gum so it was in short supply but it would be back.) I quickly discovered that the Flare 5 was far superior to the Trident and I haven't looked back. It does last a long, long, long, time. Unfortunatley, as other reviewers noted, it has become very hard to find in stores. Trident cinnamon is everywhere but now I don't want it. Amazon saves the day again.

I am only drinking it, so it won't be wasted, and I have to rotate it with a Coffee People product, so I remember why I like coffee. It is really wan. The strongest flavor profile is tin. I love creme caramel and am a huge WP fan, but the flavor strenth and consistancy of this coffee does not impress. Choose another - you won't be sorry you did.

Love, love, love these crunchy little treats. They remind me of "Munchos" but without the greasy tounge afterwards. I don't usually like flavored snacks, but these are all great, not overwhelming and no gross aftertaste. I subscribe to them so I will never run out:)
