Purchased in December 2021 and used for approximately 4 years until October 2025. Listed as junk due to a sudden burning smell. (Power turns on.) I suspect a malfunction around the motor, but I haven't disassembled it as I am not a professional. No box, instruction manual included. Please understand the above before purchasing. It looks quite clean at first glance, but I have marked the condition as "poor" due to it being a junk item.
