Try and kill it, I have put this shredder to the ultimate of tests, with the sole intention of breaking it as it was chosen by my wife and my opinion was not required. In the past if I chose something without asking her advice it usually gets broke and I get the blame. So I decided to clear out my office, three bin bags of mainly A4 paper were shredded in 50 minutes, no overheating even with continuous use only stopping for a few seconds to keep emptying the bin. After a 10 min break I then spent two and a half hours shredding newspaper, as I said my intention was to break it. I only stopped as there was nothing left to shred. We have now had this shredder for a month and it gets used every day, we are more than just casual users and it takes every thing we can throw at it. I have used many different shredders over the years and this is definately the best I have had, it looks good, it is very sturdy and amazingly quiet, there is no problem with the size of the waste bin all you need to do if you are doing loads at one time is to have a couple of bin bags next to you. I would recommend this shredder to anyone and if I do eventually get my wish to see it die I will buy another one.
Update. April 2012
Just had to order another one as I finally killed it. It can't shred canvas photos the threads in the canvas wrap around the blades, it certainly didn't go down without a fight there were three A4 sheets wrapped around the blade before it cut out. I had been using it continuously for an hour before I put the photos in it, this was the first time the overheating cutout actually cutout. I have told many people about this shredder and the ones that have bought one have all said the same as me, they are great.
I noticed that some people like a little window in the bin to see when its full, I can only suggest that this is a massive design oversight but can easily be fixed by cutting a hole in the side and selotaping cling film over the hole. (Making sure a responsible adult uses anything sharp in this process).
