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 mouth has never felt so fresh!

After my sister raved about hers, I bought my Waterpik about a month ago and couldn't be more pleased. Even after thoroughly brushing and flossing, it is amazing what the Waterpik flushes out from between my teeth. My breath stays fresh now for hours, and I feel so much more confident when talking with others. Wish I had bought a Waterpik years ago.

Wow that's clean

Really do like my Pik. It cleans and clears the hard to reach places. Especially after eating popcorn. It knocks the oil lil huskers right out of there. Ahhhh what a clean feeling.

Great design...easy to use!

This is a wonderful little water flower. Love that it's not attached to a cord! It's rechargeable and sooo easy to use! Love how clean my teeth feel after using! I fill the resovoir with warm water because I have sensitive teeth! Overall it's just a great addition to our oral hygiene regimen! Would highly recommend this flossed! Thanks WaterPik!

Portable and easily to use.

I purchased the water pik about a month ago. I have been very happy with it so far. I like that I can travel with it and it does not take up much space . I already notice that my gums look better and I am getting food particles out between the teeth easily. I am flossing less since this is doing a great job.

This great product makes all the difference!

My dentist recommended I purchase a Waterpik, due to my sensitive gums. I was a bit hesitant at first, but once I tried my Waterpik-450 for the first time, I was hooked! It cleans between your teeth gently, without harming sensitive gums, and it does it even better than floss. I love the different settings; in fact, I love everything about the WP-450. I am a customer for life!

Much better than regular flossing.

My dentist recommended water flosser at last cleaning. I choose this model because it has good features (small, rechargeable) and the price was reasonable. It was a bit of a learning curve to start using it (and water all other bathroom), but now I can definitely tell is way better than regular flossing.

Does the job

My wife and I have been using the WP-450 for over a month now. It has proven to be easy to use and clean. It takes up very little space on the counter top and the battery holds plenty of charge for the two of us. Because it is a handheld model, it does not hold a lot of water. On average, I use two tanks of water, sometimes three. If you have sensitive teeth or gums, it is best to use lukewarm water. Cold water can be uncomfortable. As for cleaning and working the gum area, it is excellent.

Easy to use

I started using a WaterPikbecause I was have gum issues. My dentist recommended that I use a water glosser. In the time that Ive been using WaterPik, my gums are no longer bleeding, swollen, and sore. I wish that the water reservoir was larger; only 30 seconds, not 45 seconds.

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.


I bought this a month ago. It really gets out the food around my teeth. I've charged it once and it still on t if e same charge. I don't always use it every day. I usually only fill it up once. I also use gum rinse with the pink, sometimes with water and other times straight. I can tell a difference!

Easy to use

I got this for Christmas and I use it every day. My only suggestion is to not use cold water. It was too cold on my teeth. I use luke warm water and its wonderful. Cleans my teeth better than traditional flossing. I'd highly recommend this product!

Love my Waterpik!

I really, really hate flossing and started looking into buying a Waterpik. After Christmas I bought one and it's the best thing I ever did, I use it every day. Between this and my electric toothbrush, my teeth feel and look great! I put in warm water, which feels great, and do my uppers and then refill and do my lowers. I use the low setting for fronts and the high setting for the back teeth and it really does remove all the stuff stuck in my teeth. My only criticism of this product is that it does not have a charging light. It would be nice to have a light like the one on my toothbrush, which blinks when the battery is getting low and stays on when the charge is complete. I only have one outlet in my bathroom, which my toothbrush is plugged into so I take my Waterpik to the kitchen on Sunday and plug it in for a few hours. So far, it's been lasting all week on the one charge. Very happy with my Waterpik!

Like taking a bath.......

I do not like this and definitely would not recommend it. If you do not keep your mouth kind of closed water goes everywhere. On the mirror, on my face, clothes and countertop. I only use it on the weekends when I have time to clean up the mess. And I only use it because it was a Christmas present from my daughter AND I HAD ASKED FOR IT. I hate it and definitely would not recommend it and share my experience with everyone. Oh and I have the setting on low.......Terrible

Better Than Adequate But Not Great

I have owned a Waterpik Ultra (WP-100) previously, but after replacing the hose/handle assembly a couple of times (the water supply tube would crack and break after a few years) and the seals once, I decided to try this model. Pros: performs as well as its bigger countertop siblings; cordless. Cons: water tank perhaps too small; a little bulky so not as easy to use as the countertop models with hoses and handles; cannot use while charging; no charging indicator/light. Overall, I prefer the countertop models.

Has a learning curve

I got this has a gift. I recently had dental implants and my surgeon said this is the best way to clean. It takes awhile to figure out the best way to use it. I have had it for a couple weeks and am finally starting to get the hang of it. It cleaning behind the teeth that has given me the most trouble. that said my teeth do feel and look better. I had a few tender spots when I first started using and those are gone. I think with a little more practice we will be getting along just fine!

Great Waterpix

I wasn't sure if I was going to like the waterpix or not. I do like it very much. It's compact and it has a very strong force of pressure I wasn't aware of the amount of water it takes to go through your teeth. I only have to refill onetime to do the upper and lower outer teeth and a refill to do the upper and lower inside of your teeth. My teeth looks whiter and brighter I look forward to water flossing my teeth and I still use my regular floss as well. I purchase my waterpix from Bed Bath & Beyond and the price wasn't bad less than $50.00. You also get extra pixs in the box.

A Fresh Mouth, But In A Good Way!

I got this as a gift for Christmas and I am really enjoying it. I recently had dental work done and am being very careful with the inlay. While I floss every night, I felt like I needed a little something extra. This WaterPik does the trick. You would think after flossing and brushing with an electric toothbrush your mouth would feel clean as a whistle and it does, but after using the WaterPik, it feels even cleaner if that is possible. Maybe it is all in my head but my mouth has never felt fresher after using this WaterPik. My only issues with it are that there is no battery indicator to let you know when you need to charge it or when it is fully charged. You kind of just have to guess which is annoying. Filling it with water is also a little messy.

Does the job

I have used this for about 3 weeks now and feel it is keeping my gum lines clean. I wish there were some way to remove ALL the water between uses as we have hard water and I suspect there will be mineral buildup. You have to learn to turn it off before removing it from mouth or you'll be cleaning up around the sink.

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.
