Review on Waterpik Blue WP-563 Cordless Advanced Water Flosser with Travel Bag and 4 Tips - Rechargeable, Portable, Waterproof, and ADA Accepted for Teeth, Gums, Braces, and Dental Care by Katie Bobzien

Waste of money. Bought for travel in Europe where my faucet mounted oral irrigator cannot be connected to hotel faucets. It was thrown in the trash after one ride – now it's in a landfill along with an unnecessary bag and other accessories. A masterpiece of bad design in every respect. Huge, heavy, ugly. Poor ergonomics: There is no way to hold the tip in a way that it gets where it's needed and moves smoothly along the gum line. The skinny tank doesn't hold enough to craft even one quadrant with care, so it takes at least 5 or 6 clumsy refills to do so. The tip needs to narrow the beam, probably to compensate for the lack of power. Although strong, it doesn't move enough water to clean effectively. It only takes a couple of days to charge, so you'll need to pack a bulky and heavy charger and cables (and a European adapter!). The tank leaks during air travel, so it must be kept in a plastic bag. I replaced this loser with a battery powered model from a major electronics company that starts with a P. What a joy!
