I've crunched through about 500 CD's/DVD's and several hundred papers and it is still working like it did on day one. If you get to aggressive or run it too fast for too long it will shut itself off for 8-10 minutes until it completely cools down. So be aware that if it suddenly stops and appears to be broken, feel the top to the left of the main switch. This area will be very hot, but not so much that it burns your hand. Turn it to off (the middle position) and let it sit for awhile. It's a safety feature, and it works very well, just be aware that it is not broken.
The trash can it comes with fills up quick and could be larger, but I can't knock the shredder, especially since the right side as you are looking down on it expands so you can put it on a larger trash can such as a rectangular kitchen trash can.
