Great
It's really good, i have early signs of gum recession and I do find that it's a bit too aggressive on my front lower teeth. I do wish there was a gentler setting just to go over those areas. Overall good product the charge lasts about 2 weeks and it works great. Bear in mind that you do have to refill it two or three times for each use.

Great Performance, Small Reservoir
I’ve been using this Waterpik for a short time, and overall I’m very pleased with it. The water pressure is strong and does an excellent job cleaning between my teeth and along the gumline. The battery life also seems very good, and I like that it’s rechargeable instead of using disposable batteries. The only drawback is the reservoir size. For a thorough cleaning, I have to refill it about three times. That sounds inconvenient, but since I’m already standing in front of the sink, refilling only takes a few seconds and isn’t a major issue. If you’re looking for a compact cordless water flosser with strong cleaning performance, this is an excellent choice. Just be aware that the smaller reservoir is the tradeoff for its slim, portable design. Overall, I’m happy with the purchase and would recommend it.

Feels like it’s working good
I really like this and how my teeth feel after use. I use it in the shower which helps all the water splash from my mouth!😅 easy to use. I used the lower speed for my first use as recommended - from then on I used the higher speed. I feel the pulsing of the water stream is good. Only used for a week so I’ll see what my hygienist says at my next appointment.

Works very well
This is a wonderful product cI have had several cavities recently and my dentist recommended this product. Since I use it every night before bed I haven’t had any new cavities. It is amazing how much junk stays in your teeth even after brushing. Wish I had started using it sooner.

Read reviews from people who've owned it for some time - not from people who've just received it.
Updated review, 04/03/26: The second Waterpik Cordless I received about six months ago leaked from the moment I first used it, so - like the first one I owned that lasted 18 months - this one has to live on a folded paper towel to prevent it creating a little pool of water on the sink surround. It works well, but I am unable to see that the design of it has changed in any way since I bought the first one. That suggests that the manufacturer is not troubled by reviews such as mine that question the quality of their product. Next time I need a water flosser I'll look elsewhere. Original review: I am having my second Waterpik cordless flosser delivered today. The reason I'm buying again a product to which I've given only three stars is that I'm not aware of any alternative similar product. If there were one, I'd definitely try it out. I owned the first one for a year and a half. Personally, I consider that unsatisfactory, but you will find reviewers whose flossers lasted far less than that. Here's what happened with the first one: I bought it almost exactly 18 months ago. It worked OK for about a year, being used once a day, every day. At some point the two-speed switch stopped offering a slower speed: I don't know quite when, because I always use it on high speed. Around its first anniversary the base started leaking slowly, so I stood it on a folded paper towel when not using it. The problem was not severe, because there was very little water left to leak after use. Nevertheless, not very good. A week ago it refused to charge. This turned out not to be a defective battery but a problem with the USB-C connection on the side. This connection is "protected" against water by a rather awkward rubber plug, but it doesn't seal very well. While troubleshooting it, it became clear that the USB-C is picky, and some plugs won't work at all. Possibly certain chargers don't work either. I urge potential buyers to read all the reviews before making their purchasing decision. It is clear from the reviews as a whole that a) the quality of construction leaves something to be desired; b) the company can be unhelpful when it comes to warranty claims. You will have to be the judge as to whether these potential issues justify the asking price. As I said, I'm purchasing a second one right now. If this doesn't do better than the previous one, I'll look elsewhere next time.

Great product and ease of use
The Waterpik Cordless Pulse 3100 is a fantastic choice for anyone. The benefits of a water flosser with the flexibility of a portable device. It excels in performance, ease of use, and battery life. While a larger reservoir would allow for longer continuous sessions, its speed, portability, and power make it a highly effective waterpik for improving and maintaining oral health. It is a solid, professional-grade product that simplifies a tedious task for everyday people.

not worth it
The water tank is very small, and the stream is weak. I had the same brand a few years ago, it was quite good hence the reason to buy this one. but this is nothing compared to the older one, too week, too small and too far to change, so be it, but I won't recommend to anyone.
