Okay Ultrasonic Cleaner for the money, I changed the power cable to a UK fused plug & check the unit was earthed & was wired correctly before using the unit . I was not happy using the EU power cable & plug that comes with the Ultrasonic Cleaner. After that it worked nice & safe, very happy with the results with my motorbike carbs & the liquid carb cleaner in the Ultrasonic Cleaner.
