Bought this to clean some Mikuni carburetors. These things looked terrible when given to me for rebuilding. After having them in this cleaner, they now look almost new. It is critical to use proper cleaning solutions for different metals though. Wish the display was in fahrenheit and not Celcius but easy enough to convert. Also the decimals on the displays do not work for me, again not critical. The heating is unreal and the ultrasonic cleaning does an incredible job. The size is perfect for my use. The bigger, then the more solution you will need to make. I DO recommend this cleaner and wish I have bought one sooner. Vevor sells some great products. Love browsing their products.
