Ultra-quiet design home shredder, A4 compatible, can process 6 sheets simultaneously. - Brand: IRIS OHYAMA - Model Name: P6HS75C-B - Quietness Level: Ultra-quiet (45dB) - Compatible Size: A4, 6 sheets - Features: Auto-stop function - Sensor: Detection sensor - Operating Time: 10 minutes I have used it for about a month since I purchased it. I think it is still fully usable, but there is a noticeable scratch on the left side. It's not deep (see photo 4). The sound is quiet. Thank you for viewing. I will lower the price slightly. Thank you.
