Bests & Worsts Reviews from Amazon

I bought one of these last year at a pet store and it was amazingly sturdy. It survived hundreds of hours of intense chewing by my terrier. Finally he destroyed it, and we immediately bought this replacement on Amazon. But *it wasn't the same thing*. It was the same shape and color and brand name, but much much flimsier. Just looking at it, we could see how the rubber was thinner and stretchier. And indeed, our terrier tore it apart easily, within 10 minutes. Investigating further, I went to a pet store and saw on the rack both the hardy and the flimsy kind of ball, with exactly the same price and SKU. My guess is that the company has just recently switched to a cheaper manufacturer that makes the flimsy balls, and I was seeing the last of the old hardy balls. Here's a trick: With the hardy kind, one of the hexagons is not a hole but filled-in, with "jw" written on it. With the flimsy kind, all the hexagons are cut out the same. Anyway, if you see that the reviews seem to be "love-it-or-hate-it", this is why: Some customers got a totally different product than others did. Mine was the flimsy kind. The customer reviews lead me to believe that everybody is getting the flimsy kind these days.
