wow,Amazing tool,you won't regret buying it.

I have purchased the waterpik cordless plus water Flosser two weeks ago.The black version. it is just amazing, all in one, great tool to keep your mouth healthy. just to be fair, it is the best waterpik currently in the market and in affordable great cheap price. I had been having lots of issues with my gum including bleeding, pockets and inflamation. I had previously purchased all versions of waterpiks currently in the market and still having them. What I found that the waterpik cordless plus has been the best to clean, to massage the gum and to really provide a healthy feeling refreshed mouth all day. you won't regret getting it. just make sure it is the plus black version.

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.

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 love the ease of use!

This is so easy to use. Yes, you do have to refill the chamber once- but it is so easy! You just flip up the little seal, pour lukewarm water from the tap directly into the water container (attached to waterpik), then flip the seal closed. It takes no more than several seconds, especially since you're standing right by the sink anyway. lol What I generally do is fill it, do all the top teeth until it runs out, then fill it again and do the bottom teeth. I think the jets have the right amount of pressure, (though "high" isn't that much of a difference, only a bit more forceful)- and it is fast to use, dry off, then set aside for the next use. I like it a lot better than the original waterpik- which I also own but found easy to eventually put aside and not use or ignore/dread because of the hassle and the irritating tubing that always seemed in the way or not long enough to reach for me to bend over the sink. With this, I don't dread the process, since the process is made so easy and portable with no tubing. And I think it cleans the teeth just as well as the original. :)

Started out strong...

The first couple of weeks I was in love! This did everything I had hoped and then some. About the 3rd week of using it, a small piece broke off from somewhere. It was floating around in the water reserve but I was not able to see where it came from. The reserve started leaking after that so I emailed the company. They had no idea what it was from either but promptly sent me a new reserve. Huge props to them for great customer service! Another few months passed and it worked great but I could feel it was losing its power. I started having to charge it more frequently but that eventually quit helping also. I now have to keep it charged at all times, only unplugging to use. Yet there is hardly any pressure. I am hugely disappointed in this! For the price, I expected it to last me at least a year, maybe more, but I have only gotten 7 months use out of it and now it is ready to be tossed.

If you hate to floss....

So I bought this because I hate to floss and hoped maybe this would be wonderful and impress my dentist. I read all the reviews first then went ahead and purchased it. I have to say you could totally use this to wash your walls, lol! It is kind of messy at first - you do have to keep your head down or just do like everyone else says and use it in the shower. I was hoping to be able to look in the mirror to see what I was doing but that just can't happen. I can clean my teeth on one "tank" full. I use the low setting and find that is quite powerful and sometimes hurts I can't imagine using the high setting. I will admit I have not got into the habit of using this yet and I have not tried out the other attachments yet. But I do prefer it to flossing so far and hopefully when it's time to go to the dentist they will say wonderful things. So while I do recommend this it's not exactly like I thought it would be.


Seriously dissapointed. As a devotee of the original style of WaterPik, one where the 'Pik' works from a separate quite large reservoir, I originally thought this cordless idea would be a winner, so bought without checking around. Oh boy. The on board reservoir is too small, so needs to be refilled multiple times during one usage. You can only do the outside surface of your gums, not the inside. The Pik rotates unstoppably within the device when in use so half the squirts don't even hit your gums. Most 'effluent' rolls down your arm to make a mess in your bathroom. Do not get this. If you want a WaterPik, stick w the unit w a separate reservoir, not cordless.

WATERPIK with large reservoir recommended but ...

My bathroom in my new place is tiny with literally no counter space but with a huge shallow depth medicine cabinet. I switched to this cordless because it would fit in the cabinet. I keep the old plug-in waterpik in the hall closet and set it up each time which is a hassle. I am a bit disappointed with the strength of the pik - even on High it doesn't have the force that my plug-in has. I bought the pik with the largest reservoir but have to fill up 3 times each use. It is convenient - It will be my primary pik. I can travel with it. But I am glad I have the back-up. I priced checked extensively and the Walmart price is great. Bottom line you have the space get the plug in pik with the bowl reservoir.

So surprisingly effective-never felt cleaner!

For the price, this little machine works very well for me. Until now, I thought nothing could beat the thoroughness of flossing, but this instrument, I clearly see, gets out a lot more--probably as close to 100% as is possible. It takes a cleaning or two to learn how to position the tips in the top mount, but when you do, you can actually get a thorough cleaning very quickly and accurately--it beats flossing. I have these deep places between my teeth that are the results (I guess) of continued replacement of crowns, etc., and importantly, this Waterpik thoroughly cleans out those holes that (I learned from my dentist) I had been completely or mostly missing even though I brush and floss regularly. The only problem I have had is trying to feel the little special sprayer meant specifically for small holes. It's probably effective, but I pretty much have decided the general insert does a good enough job of reaching deep into those pockets, so it is the only insert I generally use. I will use the WP-450 or another form of Waterpik for the rest of my life.

A Good Dental Helper

I've never used a Waterpik so this is a new experience. There is nowhere in my bathroom to hook up a Waterpik so I saw this & thought it might be helpful. It is. After using it a few times I like it and I feel it does irrigate the area around implants and under bridges and around crown work--of which I have a whole mouthful--and does a good job. Since I'm a new user it is taking me a while to get used to it. It runs out of water quickly because it's small, and it needs to be small as a cordless appliance. I believe when I have more practice the water will last a bit longer but I still expect to refill it once. I'm wondering how long it keeps a charge and that will affect my opinion of its usefulness too.

LOVE IT! Has made flossing so much easier.

I love my Waterpik flosser! I've had it for maybe 10 months now, and at my last dental cleaning, the hygienist was HIGHLY impressed with how clean my teeth are. I've always been a regular flosser and take good care of my teeth, but flossing can be cumbersome at times. The Waterpik flosser does the job of floss, but twice as fast. I feel like spaces between my teeth are getting thoroughly cleaned (even my wisdom teeth!). I love that it takes up next to no space on my bathroom counter, and that I can take it anywhere with me. Yes you do generally have to fill the reservoir more than one time but that takes a total of 10 seconds, if that. It's not that big of a deal, trust me.

Compact Feature

I purchased this product for an extended trip and it worked better than I had thought. I was able to get the clean feeling that I get with the larger version that I left at home. I wish it had a way to completely drain all of the water out of it; but I used a paper towel to help get the water out.

Really works Great!

I bought the waterpik on advice of my dental hygienist it is great! i love the way it makes my teeth feel so clean! i would highly recommend It! I have the Waterpik WP450

great purchase

I bought this about a month ago, and I love it! The waterpik has 2 pressure settings, and it gets food out from between my teeth that I didn't even know was there. My dentist recommended I get one, and I am so happy I did.

Great Job

Received this for Father’s Day gift feel very lucky

An ok product.

I bought this about a month ago; it does what it's supposed to, but it's messy.

Excellent Product!

So very happy with this cordless waterpik...really does it’s job...removes particles from under your gums, where flossing can’t get to. This is my third waterpic and will always use it!!!

Not for me....

Had to refill 6 times for single use. Very awkward to use, especially for getting to back of bottom teeth. Returned this item. Purchased WP-100 Ultra, very happy with that.

Difficult to fill

Getting water into the tiny opening is difficult. It does not have the power of the regular plug-in Waterpick.
