Product review (5 stars): Put it under the fridge for extra water damage protection.  Genius!
cut off the front and slid it under our fridge to protect our new hard wood from any water damage. The water will slide forward, alerting me if the fridge leaks and prevent water damage.  By golly, I think this is down right smart of me. It fits nicely and gives me some security about my new floors I just installed.
