Waterpik WP-450 Cordless Plus Water Flosser is rated 4.4 out of 5 by 2722.
Rated 3 out of 5 by from Annnoying I feel it needs to be refilled and recharged too often. It gets the job done but it's annoying

Rated 5 out of 5 by from Favorite present How did I ever get along without it. It was the best Mother’s Day present ever Absolutely wonderful if you have bridges or caps.

Rated 1 out of 5 by from BIG DISAPPOINTMENT!! I have always bought only waterpik products for 20+ years. I need to use a waterpik at least twice a day. This is the first time I have ever been disappointed. I can not believe how cheap this feels, hard to clean and how short the battery life is. There is NO indicator light on the unit itself or the charging cord to indicate if it is even charging or has a full charge. I charged it for 24hrs when I first brought it home. It worked fine for a few days and then slowed down so I charged it for about 8 hrs yesterday and just now it slowed down again. I would never have expected to want to return the product as I have always LOVED Waterpik flossers. I unpacked it and discarded the box. So now what? How can I get a refund?

Rated 2 out of 5 by from Works terrific when the battery works. Purchased my first one and loved it until the battery quit. Waterpik generously replaced it. Lasted 15 months. Notified waterpik they gave me charging advice and gave me an extra month. Perhaps I'll try another brand

Rated 4 out of 5 by from Bigger but not better the WP-360 had a slimmer style and was easier to hold than the WP-450

Rated 4 out of 5 by from Waterpolo WP-450 Only complaint is that I run out of water and have to refill it during my session.

Rated 4 out of 5 by from Portable, but small reservoir The reservoir is small, usually fill it twice. Have to hold it upright so difficult to do back of bottom teeth. But portable.

Rated 4 out of 5 by from Great Customer Service! My new WP-450 "flosser" developed a problem after just a few days of use. I called the toll-free "help line" for assistance. The technician who answered my call led me through a series of tests and determined the unit was defective. A new replacement unit was sent out by Priority Mail and received in just 2-3 days. It works perfectly! It's good to know there are still a few companies that have excellent customer service and will stand behind the quality of their products.
