Customer Reviews for Waterpik - Cordless Plus Water Flosser - Black
Posted by: NTVonline
Verified Purchase:Yes
This handheld model has limited functionality. The water chamber is too small to be useful. It only holds enough water to clean one quarter of your mouth per filling. Water goes all over the place when using it. I bought a plug in model to use instead. I don’t recommend any handheld version.
No, I would not recommend this to a friend.

Hello NTVonline- We're sorry you were not satisfied with the WP-450. The unit is designed to be compact for those with limited counter space or who travel. Some users may find it necessary to refill the reservoir more than once. The model does have a 30-day money-back guarantee. For more information, please contact us at 1-800-525-2774 or email smreviews@waterpik.com.

I have been using Waterpik WP-450 every night since a month ago. I just followed the instructions to use on the website. flossing with luke-warm water is very relaxing and much more convenient than thread floss.

It's a bit messy, but that would be expected; Be sure to do this over a sink!

This model would be good for traveling as it is not heavy or large and has a small attached water reservoir.
I was looking for something that does not need to be filled up with water so quickly.

Item is okay, but the tips to use are extremely expensive and Not available is stores. The surcharge for ordering is extremely high, therefore I must do without.
