Functionally OK. Ergonomically fair to poor: (1)numbers for speed/pressure too light to read without 20-20 vision- dark grey or black would be better; (2) previous hand-held applicator was round (cross section); this one is oval and more difficult to use-it turns both in my hand and on its swivel during use and does not fit as well into its holder after use.
Husband and I started using because of dentist recommendation. Researched other water pics and chose this one based on size, price and reviews. Did not disappoint! I’m almost becoming addicted to using the water pic, makes my teeth and mouth really feel great and gets all the particles out between my teeth and gums. I highly recommend this water pic.
I've been using this for years! Love the quality and warranty. If ever a problem arises it's handled quickly and effectively. Too few companies stand by their products like Waterpik.
