I like this gum, its a cool idea and I'm sure has hit the market of other brands.

I bought PUR Gum in Peppermint flavor, and was very happy with it. I bought a large resealable bag of it, and it lasted quite a long time.
I like that it's chemical free, has a nice, fresh taste, but isn't too overpowering. The flavor lasts a reasonable amount of time, and leaves nice breath afterwards. It didn't stick to my teeth, and because it's sugar-free it's diabetic friendly.

I’ve gotta admit PÜR GUM packs a punch! It is available in 4 flavors: Wintergreen, Pomegranate Mint (mommy favorite), Spearmint and Peppermint (kids favorite). It is of course completely aspartame-free. Sweetened instead with the natural goodness of Xylitol, the gum gets its great taste from Mother Nature herself! A substance produced by corn, Xylitol has been found to aide in digestion, and even prevent tooth decay. Not only that, it is completely safe for pregnant moms and children of any age. I know my little men loved it!

Only downside: the flavor doesn't last very long! :(
