I am also reaching out to acquaintances, so please check the comment section before purchasing. Therefore, I may suddenly delete the listing. I purchased this online 7-8 years ago, but I started caring for my mother-in-law soon after, and I didn't have time to use it much, so I stored it after using it a few times. There is a tear on the top of the outer box. The warranty period has of course expired. I have included photos of the operation check. I will check the operation again just before shipping, but if you are concerned, please refrain from purchasing. Please contact the manufacturer for any defects after arrival. I will not be able to assist. I am sorry, but I cannot accept returns or refunds. Thank you for looking.
