Easy set up and easy to use. I was using it the day I bought it. Really cleans my teeth, my dentist noticed the difference my first visit after buying it!
Love this just wish the brushes had indicators in them to know when to change them. Also you cannot run 2 units at same time.
I would recommend this to a friend!
