    Disappointing Chew
    Flavor Name: Watermelon, Size: 50 Count (Pack of 1)
    Starts out with a burst of flavor that quickly fizzles out and texture is grainy and unpleasant

    Spendy but delicious. Helps with your teeth, so I highly recommend it.
    Flavor Name: Watermelon, Size: 150 Count (Pack of 1)
    Flavor is excellent, really tastes like watermelon. I wind up eating about four at a time, so it doesn't go real far, but I like it. I'll keep buying it because I love the taste. It's good for your teeth because of the xlitol. BUT don't let your dog find it. It can kill a dog, the xylitol. So keep it high up where your dog can't get to and wrap it before putting it in the basket so your dog can't get to it. No sugar, so safe for diabetics! High quality, nice packaging. Highly recommended, just keep your dog safe. If you take your dog in the car, don't take this in the car.

    Not a fan of this flavor
    Flavor Name: Watermelon, Size: 50 Count (Pack of 1)
    I am not a fan of this brand of gum. I have purchased in the past Watermelon by Pur unfortunately they don't make that anymore so I tried this one. I personally do not like the taste.

    Just what I was looking for: Informative, clear, and concise
    Format: Paperback
    I've been looking for ways to learn about first aid beyond the basics of CPR and Stop the Bleed. This book is the best resource I've found so far. It is well organized, clearly written, and a pleasure to read.
