Purchased in 2023 and used for about a year and a half. The entire unit has been disassembled and thoroughly cleaned. I cleaned it carefully, but there may be some areas where slight water stains are visible due to the passage of time. Due to the structure, it's impossible to completely drain all the water, so please be sure to rinse it with water once before use. This is a used item, so please purchase only if you understand the minor scratches and signs of use.
