Customer Reviews for Waterpik - Ultra Water Flosser - White

Verified Purchase:Yes
I’ve had this for three weeks and already the seal at the bottom of the reservoir leaks when I go to refill it. It looks clean and I empty the reservoir after each use. In order to stop the water from pouring out, I need to push down on the seal each time. I’m going to contact customer support to see if this is covered.
No, I would not recommend this to a friend.

I have always liked using the Water Pik. It's a must have in my oral hygiene routine. They don't last forever, but if I can get 5-7 years out of one, I am fine with replacing it. I get my money's worth!

Previously gave a good review, but since then the rubber piece on the bottom of the tank has been continuously leaking. Pushing it in doesn’t help.

best water pik that I've used. Teeth feel really clean after use and I would not return to any other water pik. Various speeds don't hurt either as you should probably start low and then work your way up and trust me on that.
I would recommend this to a friend!

Waterpik and flossing is imperative for older people with braces. It’s easy to adjust the water pressure, and it comes with a nice selection of tips.
I would recommend this to a friend!

Adjustable strength of pulsing water to clean in between teeth and around my crowns. I have to use this twice a day. I also appreciate the portable smaller Waterpik to use for traveling= fits in my suitcase better!
I would recommend this to a friend!

Poor design. Very difficult to fill with water.

Poor design. Difficult to use. I enjoyed my previous WaterPik Flosser for many years until it finally broke. I tried to replace it with the Ultra model, but after attempting to do the most basic function -- filling it with water -- I decided to return it. Normally I would simply flip open the top and fill the tank. However on the misguided design, I can't simply flip open the top. I have to forcibly wrestle the top off of the tank without the help of any handles or other features. This is unfortunately a poor design without consideration for ergonomics or the user experience. I do not recommend it.
No, I would not recommend this to a friend.
