The reason I bought this is originally I bought a cordless water pic and it stunk. After charging it only kept pressure for a few seconds. I wasted my money on the cordless. The electric powered one works great
I bought this on recommendation of my dental hygienist since I have had gum problems and pockets that require deep cleaning every three months. My gums are healthier no more bleeding since using the water pik for a year now. Thanks to the water pik water flosser.
