Fellowes Paper Shredder Powershred 320

I work in an office where we shred hundreds of papers everyday. I use the Powershred 320 and it has its advantages and disadvantages. Some of the advantages are that it can shred up to 15 pages at a time, and has a fairly large storage bin. Ive found that the disadvantages are that when emptying the storage bin it can be messy and the bag tends to slip from the edges. It does need to be greased frequently, which can be messy and until the teeth are completely lubricated the machine makes a horrible loud screeching and grinding noise. The machine shreds plastic and Cd's with ease. The machine isn't very quiet, I would say its pretty noisy which can annoy others if they are on the phone. The Powershred has a lot of power but tends to be pricey, this machine will set you back for around $800.00
