My purchase was justified by a TV report which explained the dangers of throwing papers, labels to an address in the bin (large scale scams, making false bank cards etc ...) I chose the Powersherd P35C for its ability to cross-cut. Do not like me. Forcing above 5 sheets = lock the device, dismantling and 2:00 to wrest the tweezers ripes the paper jammed in the teeth. Not for heavy use and do not forget to regularly lubricate the teeth. Very good device, delivery on time. I recommend this device.
