Right out of the box I put this baby to the test. It does what it says it can do and more. I ran it for an hour straight with no problems. Let it cool down a bit (but did no need it). I was a bit scared when it hit a dime glued to my junk mail. It kept on going . I was going to spend $109.00 on a professional shredding service but went for another $50.00 and bought this machine. No complaints here. I did about 100 plus pounds of documents in total.
