Rated 2 out of 5 by from great features, but battery poor. I bought this 18 months ago. After a year the battery has been undercharging, and even required new charge after 2-3 uses. And then it was not charged enough. I took the entire thing apart, and discovered that the motor was charged, but the pressure to push water through the channels overwhelmed the motor force. Once put back together it did better for a few weeks, but now is back to dying after only 2-3 uses.

Rated 4 out of 5 by from Waterpik wp-450 Water spashes on to my chest often and wet my t-shirt often. When charging the hardware, no light turns on to indicate that the system is charging, or fully charged and not taking any charge, so I can pull the plug. Otherwise a good product in general.

Rated 4 out of 5 by from Better batteries This is my third Water Pik in 3 years.The first one I was given to us by our dentist.The next two were sent to us from Water Pik because the battery would not charge.I think a better rechargeable battery would serve the company more profits rather sending out a new one every 6 or 7 months. I do have to say that the company warranty is outstanding in that the company has replaced the old water pik in quick response.As far as the performance of the water Pik , it is outstanding and refreshes your mouth after use. Each time I have called the customer service Rep.has given me different instructions on how to charge The previous Rep. told me to keep it charged all day long as it was used 3 times a day.This last Rep told me to just charge it over night and keep it unpluged during the day

Rated 4 out of 5 by from Try it, you'll like it, better than floss I need four new crowns and catch food particles at receeding gumline. I like the cordless waterpik because it gets the stuff blasted out and it is quick. I have the big unit but never took it out of the box because of the size and cord. I recently got the cordless model and use it all the time. I wish waterpik would come out with a mini blaster to carry during the day so you can blast off the stuff after lunch in a restaurant just for your problem areas. It should be small, easy to use and priced reasonably. This could be a huge seller and with the baby boomer market needing more dental attention due to age, the profile is set for a demand market. Someone please read this and get to work on it. Thanks

Rated 4 out of 5 by from Overall SO much better than flossing . . . . I hate flossing. So I rarely did it and have therefore not looked after my teeth as I ought to have. Every time I'd floss, I'd cut my gums, and it was never a thorough job. Waterpik is a great product. It simply works. No more cut gums. Gets into hard to get to places. Thanks. Don't normally write reviews but this is a good product. Nowadays we are inundated with new things claiming this and that and not delivering. This one does what it says it does. I've only given it 4 because I have to refill usually before I've finished. Which is only a minor thing of course. Also I have yet to find out about it's longevity ...

Rated 3 out of 5 by from The WP-450 is more bulky to use then the WP-100 The unit is more difficult for me to keep from dripping down my arm. I bought the unit for traveling, maybe with practice I will like it as much as the ULTRA WP-100.
