Difficult product to review
This product works well if you soak the contacts for 6 hours or more. The metal in the container reacts with the hydrogen peroxide and makes lots of little bubbles that do a good job cleaning. The problem is if you forget to wait 6 or more hours and put them in you will feel pain that will make you roll on the floor. I am not kidding about this. You will be out of commission for a while. It happened to me and I can’t believe they haven’t been sued out of existence. I think this will be absolete once people learn about ultra sonic systems.
