Excellent

Jeniffer February 2, 2026

I'm very happy with this Waterpik. It's easy to use and does an excellent job cleaning between teeth and along the gum line. My mouth feels much cleaner and fresher after every use. The water pressure is adjustable, which is great for sensitive gums. It's a great addition to my daily oral care routine, and I've definitely noticed healthier gums.

It's Amazing!

MNRN March 3, 2026

I love my cordless waterpik and have been using it for 3 years. I also have a battery operated one for traveling. I initially used it daily but had to replace batteries too often as I used it several times daily so switched to the cordless. It's amazing how well it cleans your teeth, even after flossing. Wish I would have bought one years ago!

This Little guy has saved me a lot of money

Ltrees May 25, 2021

This little guy just saved me 1500 $ visit to the dentist. I thought I had a cavity and went to the dentist, they told me I had created a pouch in my gum that was collecting food. There solution, was to scrap my gums for a price tag on $1500. DOLLARS. being retired that is a lot of money, so I told them I would have to wait. As I left the gal at the desk, that was seating up my next cleaning appointment, whispered to me to get a water pic. I told my friend and she say this is the one her husband uses, so off to Walmart online I went. Best, money ever spent, and best whisper I ever got.!

Highly recommended!

Danielle December 25, 2025

I've been using the Waterpik Cordless Plus for a few weeks now and I'm really impressed. It's compact, powerful, and very easy to use. The two pressure settings are great — gentle enough for sensitive gums but strong enough to remove food and plaque effectively.

Great Alternative to Traditional Floss

Yelyzaveta December 12, 2025

It cleans deeply between teeth and along the gumline much better than traditional floss, and my gums feel healthier and less sensitive. I love the cordless design — it's compact, easy to use, and perfect for travel or the shower. The water pressure is gentle but effective, and it only takes about a minute to use. Highly recommend for anyone with braces, sensitive gums, or who struggles with regular flossing.

I love the portable WaterPik, I can take it to work with me daily. The product fits in my small hands and it is not awkward to use. The jets are more powerful than I thought it would be. It works like a conventional Waterpik. I would recxome d thus to my family and friends for their oral hygiene care.

It is not the best waterpik I ever had, or the most powerful. It was the only thing in my order I was not totally satisfied with. Price was high for what it is.

learning curve

Jackie Dee January 12, 2026

I have some concerns. First, it takes at least 3 refills to get my entire mouth done. Second, the water adds to the weight of the water pik. Third, my thumbs have a little arthritis, so this is not easy to maneuver, turn, change speed, etc. Fourth, the place where the charger plug goes needs to have some kind of cover so water doesn't get in. It is impossible to keep this appliance dry while using it. I'm also not happy that the plug/box, whatever you're calling it, was not included. Sure, I could charge it by plugging it into my computer, but why do I want my oral hygiene stuff sitting on my desk when I have a perfectly good electric outlet in the bathroom?

Serves Its Purpose

KB2G May 20, 2014

I have only had it and used it for a couple of days now. Even though I am not as excited as when my dentist first told me about it, and when I ordered it, I still like it and it serves its purpose. Meaning, if you are looking to free up counter space, and want to travel with it...yes! And because it's cordless, I will probably use it more than my other one - which my gums will love! The downside is, it's bulkier than the picture indicates, so I can understand some of the complaints from those with really small hands. But, its not that bulky, and if you adjust your grip to the upper portion you will be fine. Plus, I think its designed for you to hold it at the top. The reservoir holds about 8 ounces or "45 seconds" (which is what the box says); which may sound like a lot, but I found it to be only enough water to floss one quadrant of my mouth, and that's using the low setting. Of course its travel size, and can only hold so much - Just be prepared to refill it a few times. Because of the refills (and the splash), I will likely start using it in the shower, but not sure if that's recommended. You also have to hold it upright. That's not a big deal. But, if you are used to holding your standard waterpik at several different angles, you'll have to adjust to that too. All in all, I do like it, and am looking forward to healthier gums. Hope this helps!

I so wanted to like this but it's not for me I have MS and the unit is big for my hand My right side is weaker so it's difficult to hold in my hand. The stream of water is not that forceful as well. I have to purchase the bigger Water Pik with the water reservoir
