Which CD shredder is good?

Unlike other hardware, shredders can't find relevant evaluation, so they can only buy expensive ones to see the parameters and so on. Kemi has a patent right. It looks great. It is satisfactory to break five dollars at a time, but it can break 500 dollars in a row 10 minutes. The paper shredding level is that a piece of A4 paper is shredded into 3899 segments, which is also very good, better than the average 20 segments. Safe touch stop technology looks good, even though no one wears a tie at all in the office. Overheating shutdown, barrel pumping shutdown and other functions are common and must be possessed. Generally speaking, this kind of shredder can also crush the staples of the stapler (that's how it is written and made anyway). The sound of shredded paper is not silent, similar to the sound printed by a printer. Because the paper is broken into many sections, the speed is about 5-7 seconds/serving (A4 paper), which is slower than unencrypted paper, but look at the effect in the photo, how nice. The disadvantage is that the appearance needs to be improved, not fashionable enough, and the buttons are not good-looking.
