Please use the dedicated button for price negotiations. I will generally accept offers. There may be some scratches from use, but it has hardly been used. There is no hydrolysis of the buttons. I have checked all the functions before listing it. There are absolutely no problems. Regarding the long, thin rubber feet on the back, they were not there from the beginning, so I have attached non-slip stickers in four places. Please refer to the photos. The main unit has hardly been used, and I don't plan to use it in the future, so I am listing it. It is like new, but since it has been in someone's hands once, please do not purchase it if you want a brand new, unopened item as a general used item. Also, if you have any questions, please ask before purchasing.
