The button is not turning on. What should I do?
Please be aware of the blue plastic label while changing the batteries. First look to see if the blue shim is stuffed in the top of your unit when changing the battery. There is a chance the blue shim stayed in the flosser during the changing of batteries and got shoved up to the top of the unit, preventing the proper electrical connection. To prevent this from happening to you, please make sure that when you change the battery, the blue shim comes out and you replace the current batteries with Duracell, Kirkland, or Makers Mark batteries.
If, after you have done the steps above and the button still will not turn on, please email us at support@slateflosser.com and we will exchange your button or product free of cost
