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.

Works fine for my Podcasting needs. I use it with a sure SM58 microphone. It is made of plastic and does feel cheap but I have had it for a few months and had zero problems with it. For desktop use it should be fine. Works great for my needs. Wouldn't recommend for heavy use on a stage or being tossed around.

We are into our third can of this flavorful and easy mix and it just seems to get better and better!  Sunday is pancake day at our house, and today we had blueberry pancakes with real maple syrup.  This mix holds fresh blueberries nicely - don't over-mix the ingredients and you will get nice, fluffy fruit-filled (or not) pancakes that are absolutely first-rate.
