Nice punch with good gripper base and collection tray for particles. Although 15 sheets fit into punch I only have the strength to punch 8 sheets. I am a 73 year old female and weigh 140 lbs. I can punch 4 or 5 sheets easily. I punched 8 sheets using both hands and some strength. Absolutely could not punch 11 sheets. Overall recommend it but it is not what its cracked up to be.
