Buying this shredder was the worst thing I could have done. It's not a safe shredder, because it has an auto on/off switch. While it wasn't in use my 8-month old puppy knocked it over with her paw. She then tried to pick it up with her mouth, and her tounge got stuck. It shredded half her tounge into little strips. We had to rush her to the vet where she underwent 3 and a half hours of very expensive surgery. Because of this shredder, my puppy has a damaged tongue. If anyone has puppies, cats, even young children DO NOT BUY THIS SHREDDER!!!!!!!!!!!!
