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.

Works great, but minor issue

I had a cheaper Waterpik model before I got this one. That one lasted awhile before it would not cooperate with warm water as the jet stream just slowed to a crawl, as if the battery was dying. However, using cold water was just fine. Hopefully this new model doesn't experience that issue. I took one star off of it because the water reservoir is rather small (doesn't last as long as the cheaper model) and is slightly difficult to fill up and empty if needed due to the opening placement. The opening placement does allow you to refill as you use it though with careful placement under the faucet.

Bulky and messy, but waterproof

I have been using this for about 2.5 weeks. It's convenient if you take it in the shower but quite bulky. It's messy if you use it over the sink. The compartment that holds the water doesn't seem quite big enough, but if it were bigger the waterpik would be even bulkier.

Very satisfied

I bought this produce to use in addition to flossing and using an electric toothbrush. I felt it could help specifically with the gum-line in the front and back of my teeth. I find the product easy to use and clean and almost "fun". It makes me feel that I have finally found a way to take care of my teeth perfectly, with the combination of this, flossing, and brushing. I have no complaints about this product whatsoever.

Great product!

I have been using this waterpik for about 2 weeks and I love it! I had braces placed about the same time and this helps keep everything clean clean clean! I am a dental assistant and as a professional I cant believe I waited so long to get one of these! I have been recommending this to everyone that has braces, crowns or bridges! I love that it is portable so that I can take it in the shower and not splash up the sink or mirror! Great product! And it even came with several different tips! My husband has been using it too and just had his 4 month check up and his perio humbers have improved considerably! Again this is a great product everyone should get one!!

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.

Good product. Some design flaws.

I think the cordless flosser is a great idea, however, it is clumsy to use. I feel as if there were a tube attached to the mouthpiece, it would be easier to use. Have the mechanical part sit on the sink and maneuver only the mouthpiece section. Also, make the water reservoir more open so it is easier to clean.

Mouth feels so clean after use.

Waterpik has been so kind as to provide me a 2nd unit without a receipt, after the 1st quit working. I am so in love with this experience, as is my dentist, that I love how well it cleans between my teeth. It feels like a dental cleaning almost and makes my gums feel so healthy.

A professional dental cleaning at home everyday!

Love the "handiness" of the product without having to worry about the electrical wire plugged into the wall. The hand-held device is a perfect fit with the finger molds on one side of the WP-450 and operational buttons on the other side. The simplicity of the design and operation of the WP-450 help make it an effective - yet gentle - way of promoting healthy gums and teeth.

Love it!

My husband uses the regular water pik and loves it- but it's too cumbersome for us to share and I didn't want to clutter up my counter with two of them. This is perfect. I always flossed but my teeth feel soooo much cleaner with the water pik. And this portable unit is super easy to use - and travel with. I'm buying one for all my kids and grandkids for Christmas!

Great product but only lasts 6 months!

I need this device because I have braces and use it to clean out food debris after every meal. I have now had 3, and every single one of them develops a problem after less than 6 months. My latest is less than a month old and the clip on the bottom has fallen off.

Great for travel

I picked this up when my counter model went down. I needed one for travel anyway. It's a bit loud, but definitely gets the job done. I love that it's rechargeable and travels well in the suitcase thru the baggage destruction area. No breaks! All-in-All, I wouldn't want to use it everyday, but am thankful for this unit for traveling.

Easy to use!

Product was purchased at the suggestion of my oral hygienist and it is easy to use. I have only been using it for a short time and not certain of the results. My concern is that the product does not have indicator for either needing a recharge or if the unit is fully charged.

Excellent product!

This is the second time that I have purchased this product. I love it! The first one lasted several years, and may just need a new battery. The product works as intended. I like two different tips. One is used over my implants and the other for general rising after eating.

Works Extremely Well

I bought this about a month ago, and I am extremely pleased with it. I fill it with half Crest Pro Health Rinse and half warm water, and clean around my fairly new, and very sore caps. It really does a great job rinsing the food out from under the gum-line and between the teeth. I then run plain water through the water-pik to rinse the solution out of the machine, dry it, and plug it back in to charge. It does an admirable job, takes very little time to clean and dry, and is comfortable to use.

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.

Impressed how effective

I bought this product over a month ago. I was a practicing Dentist for fifty year and always thought the water pik was helpful but not a dramatic help in plaque removal. I am now impressed with its ability to remove plaque.

Better than flossing, but probably not effective.

I bought this a few weeks ago and thought it would be better. The stream is not powerful enough on high, and it also runs out of water quickly. I usually fill it up 3-4 times per use. I haven't noticed a difference in my teeth or gums either.


I have had this Water Pik for approximately 1 month. Love it! I also like the fact you don't have to plug it in to an outlet to use except when charging. I use it in the shower with warm water and it really feels great. My gums like it too.

Holds battery power for at least week

Seems to really do a good job much less messily than dental floss. Comfortable pressure. Leaning over sink easily contains the overflow. The only disappointment is that it's battery is not replaceable. Considering this disposable seems wrong.
