I have mixed feelings about this product. I bought this because my puppy kept breaking the squeaker in his squeaker toys. I wanted something where is the squeaker was more durable. This was definitely more durable, it was also 10 times louder than the squeaker in his squeaker toys. He would squeak it all day and night and I could barely hear anything over it.
