Once you have used this cordless water flosser you will wonder how anyone could want the tank and cord models.  I now use this twice a day.  It is great and less mess.  So far,  ten days and counting on the first charge.<br /><br />Two years and two months,  it will no longer take a charge,  it is DOA.  so a nice product with a two year life
