Summary: I had a Fellowes shredder for the past almost 20 years. It finally had a problem and I wanted to replace it with another Fellowes machine. This was the perfect replacement. It is quiet and shreds papers in small pieces - allowing the user to not have to empty the bin after only a few shreds. I only wish the wheels had locks because mine in on a hardwood floor and it moves too easily, but that might be advantageous to some people.
Summary: First off let me say I've been in Engineering for over 30 years and I know a design flaw when I see it. The 99CI has a 9 gallon waste bin but you won't be able to fill it up past 3-4 gallons before the filled sensor is tripped and shuts down the shredder. It's happen to me 10 times in a row. The shedding gears are under the top off to the left side of the unit as you are facing it.
Summary: I only wish I had bought it sooner. It works very fast, is pretty quiet, takes credit cards, etc., and indicates when you need to either push down or remove the paper shreds. Usually all you need to do is push down/compress the paper. Once full, just dump it out and keep on going. It goes for a long time without needing a break. I use mine without the wheels.
Summary: I needed a home office shredder that could handle a a large volume of paperwork and the occasional CD or credit card destruction. On the first day I shredded about 50 lbs of old bills and it was no problem. My only complaint is that changing out the bags is somewhat messy - lots of little shreds fall outside the basket so keep you vacuum cleaner close. They should do a better job designing some way to attach the bags to the disposal basket.
