If you like your popped corn small this is for you. Taste is good and it is crisp yet tender. The only real complaint is it has a disproportional amount of hull.

Wrigleys' 5 FLARE sugarless gum is Wrigleys' sugarless replacement for their "Big Red" cinnamon gum. 5 flare seems to be difficult to find in stores. Thanks to Amazon I always have a supply. 5 FLARE is also the longest lasting gum I have ever experienced both in flavor and durability. It is positively the best cinnamon flavor currently on the market.

After years of drinking Red Bull, Rockstar, Monster and some others, I have found the holy grail of energy drinks. It kicks in within 2-3 minutes and it lasts an entire work day. After seven hours or so, you gradually come down. There is no anxiety or disphoria when it wears off. You just get very sleepy when you finally rest.  Redline Power Rush is the very best product on the market. If it were illegal I would buy it on the black market. 'Nuff said.
