Pros: Durable, Sheet Capacity, Jam Free, reasonably quiet
Kudos to Officemax for ultra-quick delivery. This is my 3rd Fellowes shredder (over a long time span). Lots of new features. My favorite is the casters. I couldn't tell which set of numbers in the ID label was the serial number and so called Fellowes. Customer service was great. The rep did my registration as we talked and he walked me through the operation of the CD and credit card shredding feature (which is really just frosting on the cake). The old way of feeding in credit cards works. He alerted me to the importance of lubricating the mechanism EACH TIME I empty the basket. Basket bags hang better in this model than in my prior one. Safety on-off master switch is where toddlers are unlikely to find it. Haven't tested the "do not shred finger" guard.
So far, it has been jam free, cross cut, 6 gal capacity, 12 sheet shredding capacity, pull out bin is very easy to empty and great safety features. I would recommend the PS-79Ci to anyone for home and small office use.
This shredder cuts incredibly well. The only complaint I have is the shred bin. It does not hold much and fills quickly. I spend a lot of time opening the bin and compacting. Also, the bags are fairly worthless and shaped in such a way that it is difficult to fill the bag all the way and then tie it off. My former cheap shredder didn't have the capacity but was very easy to empty and did not require specialty bags.
