Was it worth $20? Sure. I had fun. Dogs like it. And I've wasted more time and money on worse crap. If you want one too, take a look at the "as seen on TV" section of Walmart or Walgreens. I'm sure you can find it cheaper than what they're going for online.
So, what kind of crap have you wasted time/money on lately? Inquiring minds want to know. -- K
