Water Bottle Toys

Does your dog like to play with your empty water bottles? Apparently, Fat Cat, Inc. figures if you can't stop them, might as well make it safe. Since dogs can't resist the crunch of the bottles, they've created Water Bottle Crunchers.

Sized for empty plastic bottles 20 oz and smaller, all you have to do is place your plastic bottle in the cruncher. And when it's all crunched out, just take out the old bottle and put in a new one.
The set of two toys above cost $21.95. I haven't actually tried them to see how they handle my toy-destroying dogs, but for that price, I'm not sure if I want to take a risk. However, I admire the invention. If anyone has tried them, let me know what you think.
