This Review Title is Outstanding functionality and great price! and the content is: This is not actually like the big bulky Waterpiks that I remember.  It's just the right size and it's a dual combo...it also comes with the portable Waterpik that you can take with you when you travel (dual voltage).  UPDATE:  I loved this flosser so much that I recommended it to my brother and discovered that the other models have an on/off button on the device handle.  This feature would be a nice to have as this model you have to depress the button and hold it to keep the water from spraying out when you are moving it back to the base holder and transitioning to turn the unit on or off..There are other information for this review, one is This reviewer did purchase it and the other is 31 people think this review is helpful.
