I have been using this ultrasonic cleaner for several months now, on a variety of different projects. The majority of its use has been on motorcycle and auto carburetors. It is a very effective solution to cleaning parts and tools, and has demonstrated very good results. It is a bit noisy, but that is to be expected. The heating and timer functions work great, and I can easily have it running in the background, cleaning parts, while I complete other tasks on my projects.
