Bests & Worsts Reviews from Amazon

I bought these to replace a used up scratch pad and thought it would be nice to buy 5 at a time instead of just 2. I didn't really pay attention to the brand and the reviews were overwhelmingly good, and really, how different could one rolled up wheel of corrugated cardboard be from the next? Buyer beware, because the answer is A LOT. These fit fine into the space on the toy, but they fall apart instantly. My cats get zero clawing satisfaction because the rings just pull apart instead of providing traction and clawing satisfaction. When the first one was instantly dismantled, I thought perhaps it was just the one off defective one, but the second one was just as bad. Horrible, horrible product. I wish I could get my money back!
