I received this item, which was purchased at the beginning of this year. It is being sold to raise funds for the purchase of a higher-end model. There is one minor issue with the specifications: when adjusting parameters to your preferred values by touching them, you would normally select +/-, or slide the parameter left or right. However, the plus/minus signs are not displayed, so you must use the sliding function to make your selection. But this did not affect the functionality or operation at all (in my opinion). Regarding other operations, there were no issues within the scope of my usage. (A proof of purchase from the retailer at the beginning of this year is attached separately.) Therefore, this is a sale of the item in its current condition, as confirmed by me before listing. Please understand that I offer no guarantees or warranties of any kind, including the above-mentioned issue, so please purchase with this in mind. For product details, please refer to the manufacturer's website.

Please consider carefully and make your purchase only if you are satisfied.
