I purchased this for use in a copper/zinc/nicket plating project. They general idea is to use it to help move the bubbles away from the cathode to make the coating more even. This worked as desired, though I can't really tell if the final results were necessariily improved. I have another stirrer with a heating element. This one is just a stirrer but is otherwise perfect for the project.
