To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
These are expensive sqeakers and when they arrived I was really impressed as they are very large and seemed very sturdy. So I spent on afternoon replacing the sqeakers in the dog's toys...the plush toys which cost a lot to buy. Even though they were supposed to squeak when punctured my weimaraner managed to destroy the whole lot...six toys..in under two hours and none of them now squeak. She realised that the head of the squeaker is weak so went at them that way. Do not waste your money buying these they are just not worth it.
