Purchased on Amazon in March 2025 for 40,000 yen, Used only once. Used for about 30 hours over two days to clean a carburetor with Sunscreen. It has been stored unused since then. It has a large capacity and can control the temperature, so I think it can be useful for restoring motorcycle and car parts. There is some white detergent residue on the inside of the stainless steel, but I will clean it as best as possible before shipping, although it may not be perfect. It's convenient because you can ultrasonically clean a lot of items at once.
