I bought this model to replace a cheap supermarket shredder, but I'm sad to say that it is just as bad. It claims to handle 6 pages at a time, but this is simply not true.
I find that you can shred about 10 pages a session, at 2 sheets a time, but then you have to leave it to cool down. Anything beyond this and the machine chugs to a halt half way through a page. A major blockage is then inevitable, as the reverse function guarantees a jam. Even the old supermarket model that cost a fraction of this machine's asking price didn't have that failing.
I've only used the machine a few times, but I have already spent a long time picking jammed paper out of its teeth with a pair of tweezers, trying to coax some life back into the thing. The simple truth is that it's just not very good. In fact, it is spectacularly far from good.
