This ultrasonic cleans great! The power cleans twice as fast as my old unit that I replaced. There are only a few minor items I wish they would change. First is the annoying beep that happens when you push any of the buttons. It is very loud and I wish I could turn it off. The lid has a depressed part in the center and a strap to lift the lid. For my own purpose I wish the lid was flat without the depression. Even so, the strap across to pick up the lid is thin and sharp. It feels like it will cut me, so I don't use it. The last thing I would wish for is a button to convert the temperature from C to F. These are all minor issues considering the value of the ultrasonic, which I am very pleased with overall snd have already recommended to others.
