We replaced a Staples professional series 10 yo machine that was tired. I would have preferred to find another machine in the professional series but it is no longer available. The repacement works OK but is sig. louder than the previous one. In addition the shredded material is less granular than before (larger pieces). Time will tell how long it will last.
If my 90 year old can handle it I know it's easy to use! Wheels are great too for moving it around the house. It's pretty quiet also. A nice modern replacement.
