This product has some major disadvantages.1. The instructions are terrible. No diagrams, just vague descriptions.2. The mount design is terrible. Rear legs that are too short will cause the top-heavy unit to lean forward and put pressure on the mounting bolts. This will cause sheet metal warping on the ultrasonic cleaner.3. Fastening screws have no seals. That is, to tighten them enough to prevent the device from tipping over, you must tighten them just enough to penetrate the sheet metal.4. The motor, as others have pointed out, is too fast for the system to work and defeats the purpose! Asking $179 for a device with such flaws is really bold. I am a designer by profession. This product does not appear to have been tested. It's like "version 001". I'm so outraged by this that I'm seriously considering making my own device to compete with it. Wewu should hire the best engineers.
