Absolutely WONDERFUL Product!

First let me say, I HATE FLOSSING! But it's necessary for healthy gums and teeth. The Waterpik Cordless Plus Water Flosser arrived on 5/14 and I charged the unit for 24 hours before use. I tried it for the 1st time on 5/16. It is so easy and quick to use. I love it! I actually used it several times yesterday because it really feels good, plus your teeth feel extra clean cleaning between the crevices. I plan to order some different water flosser tips for this unit. I highly recommend the product.


My previous WaterPik, traditional model, stopped working and needed to be replaced. When I went to purchase one, I saw this model and thought "oh, this will be great. It will travel great, not take up so much space, etc." I was hugely disappointed!! It was cheaply made, leaked water, was difficult to add baking soda to the water and I hated it. Hated it so much, that I gladly went back out and bought the traditional model. I am a huge believer in Waterpik and its' effectiveness, but not this model. Do not waste your money.
Thank you for your feedback! Please note use of baking soda may impact the performance of your Water Flosser product.

Great product

Purchased the WP-450 about 6 weeks ago. Great product with manual adjustment for force that can be increased as you get use to it. Also very convenient to take In the shower to avoid the normal mess. After use set it on sink and proceed with my shower.

Battery pack not holding charge after only 8 month

Overall I liked the Waterpik Cordless Water Flosser until recently when it seemed to lose it power. Started charging everyday and that helped. The battery pack is already going bad. I opened up the unit and water has gotten inside and is corroding the negative end of the battery. Waterpik has a design flaw if water is migrating into the unit.

Wayyyyyy Better Than String Floss!

Went to my dentist for a cleaning, and like always she tells me I need to floss more. I told her I use floss sticks and sometimes regular floss, but truthfully not everyday like I should. So I asked her if their was something easier I could use that would work, and she said you need to get a Waterpik. She said that it is 100 times better than floss and more effective. So I went and bought the WP-450 and couldn't be more happy, I use it everyday, sometimes twice a day depending on what I ate, and it works Awesome. If you hate regular floss like I do, get one of these you won't be disappointed.

Best thing made for both braces and dental work

This will make Waterpik number 8. I originally bought the older version in 2012 for my dental work and when my daughter got braces in 2014, I got on for her. Then my other daughter got braces in 2015, so she got one. My first one stopped working, so I bought the Plus model, and a year later I upgraded the girls and let them bring the older models to their Mom's house. My son got one in 2017 for his braces, and one went to his Mom's house. Then, the bottom let loose on my plus, so I bought the one I'm writing a review on now.

A one year lifespan

I have had three of these in four years , other than I only seem to get a year out of them, they are a great product. The company has had no issues with replacement due to a two year product warranty. Lots of power when kept charged regularly. I use it multiple times everyday so it needs to be charged once weekly. Using the Waterpik daily is more effective than just brushing alone for optimal dental health.
We are sorry that you have had issues with the product. If you are using the product multiple times a day, it needs to be charged more than once a week. We would like to get more information about the situation and have reached out to you via the email address that you provided. Or, you can call us toll free from Canada at 1-888-226-3042 Monday through Friday from 7:00am to 5:00pm Mountain Time for assistance.

It's cordless!

I bought this because my dental hygenist highly recommened it. I like it a lot, but, it can be a bit messy at first. I have to remember to turn it off before I take it out of my mouth! I'm looking forward to my next cleaning appointment to see how big a difference it will make.

Thoroughly clean

I use my water pick based on the advice of my dental hygienist. Since I have some deep pockets in areas of my gum, she told me that using a Water Pic will help clean particles from the pockets thus prevent further gum damage. I am anxious for my next dental appointment to find out if it has truly been a benefit to my daily hygiene regime. It seems to be working great and wish I had started using it months ago.

Deep Cleans!

I bought the this because I recently got braces and was fed up with the struggle I faced when flossing. Now, I am able to clean in between my teeth easily, and I can get food out of my braces with the orthodontic attachment. Now, my mouth has a clean feeling after water flossing.

WaterPic Portability

I purchased for the travel portability. The Waterpic does a great job of supplementing my flossing and i wanted to be able to continue this when traveling. I would have given a higher rating for the unit with a battery indicator light or guage.

Great Product

Purchased it several weeks ago and immediately began using daily at bedtime. So much easier to use than softbpicks and makes my mouth feel clean and refreshed. Looking forward to mixing in a little mouthwash soon.

Waterpik cordless

I'm very happy with the 462 cordless flosser. I move the jets around as I go from top to bottom and inside and outside of my teeth because the side of the unit which plugs in has to have water access.

Easy to use

I bought at the suggestion of my dentist...a little to get used to but overall pleased with it; hopefully my dentist will notice the difference my next visit!

Really like it.

Worked great until battery needed a charge. Battery would not recharge ! (Used twice a day. ) Customer Support sent out a new replacement. They also told me at that time that the unit should be charged frequently, not just when the battery starts to run low ! That instruction is not in the operators manual. Needs to be there. I now keep it charged and works fine. Suggest device have led's indicating battery strength for charging demands.

Great Product

I am very pleased with the performance of my WP-450. I had no idea of how effective it would be. I always prided myself on what I thought was excellent oral hygiene, but the water pic is the last step to truly clean the gums. So glad I purchased this product.

Works great

I've been using my waterpik wp-450 for about a month. I've never had one before. It was a little tricky to get used to. After some days of spraying the bathroom with water, and much practice, it's kinda fun. Really squirts fast! The only negative, is, it is pretty loud. I'd recommend it, though.

I hate Flossing

This has helped me increase my oral hygiene. I hate flossing so this makes it easier to take care of my gums and teeth. With two bridges I'm not as worried about getting up on the gum line because of the added head. I have put a mirror in the Tub/Shower because it's easier to catch all the water and so I can make sure I get all my teeth. I have enjoyed using it ever time.

Fair but not thrilled!

I bought the Waterpik about a month ago....I was excited because it is a Cordless and I thought I would like it better. The only problem is the reservoir is not large enough to hold enough water to clean my entire mouth. I have to fill it at least twice each time. Not sure what I was looking for but I will use it until I can afford another one.

Effective/Comfortable Cleaning.

I purchased a WP462W unit approximately three weeks ago at the recommendation of my dentist. I am dealing with the results of Bruxism,which was undiagnosed until recently and my current dentist felt that the increased level of cleaning would be healthy/helplful in addition to the dental-night guard. I am very pleased with the new levels of cleaning that I have achieved with the Waterpik in just the past few weeks.I use the unit after each meal and am actually looking forward to my next checkup.
