Effective and easy
Easy to use and no question it gets lots of particles out of my teeth. Better than floss. Highly recommended by my dentist. Portable and waterproof. Use anywhere. Charge lasts a long time. Water fill lasts about 45 seconds. Liking it.

Waterpik Cordless Pulse 3100 Portable Water Flosser, Rechargeable
I've been using this Waterpik for a few weeks and really like it. It's easy to use, holds a charge well, and leaves my teeth feeling much cleaner than brushing alone. The cordless design is great for travel and doesn't take up much counter space. The water reservoir could be a little larger, but overall, it's a great addition to my dental routine.

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.

Convenient, portable size. Good price. Works well.
This is the second one of these I’ve purchased. The first one still works fine, but there’s no way to empty all of the water out of the reservoir, so I always have to leave it open after use. Unfortunately, I accidentally left the reservoir closed after using it once, and the tube inside that delivers the water into my mouth grew mold. It happened within a few hours. I’m not confident that anything will completely remove the mold, so I don’t feel it’s safe to use anymore. So, I bought a new one. This was an error on my part, and not a problem with the device itself. It’s a convenient size, and I like that it doesn’t take up much space on my counter. The reservoir is a little small, and sometimes I have to fill it twice, but that’s a trade-off for the compact size. It’s easy to use, and it’s improved my gum health, and it gets to areas I can’t reach with my toothbrush. It’s a good value for the price. I bought it on sale.

Easy to Use and Great for Everyday Flossing
I really like this Waterpik. I wanted something that was easy to use and didn’t take up a lot of space on my bathroom counter, and this has been a great fit. It’s cordless, so I don’t have to deal with a cord getting in the way, and it’s easy to grab and use. The water pressure is strong enough to feel like it’s actually cleaning between my teeth, but it didn’t take me long to get used to it. The size is also convenient and it’s easy to hold. I’ve been using it regularly and my mouth feels much cleaner after using it. Overall, I’m happy with it and would recommend it if you want a simple cordless water flosser without a lot of fuss.

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.

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.

Great flosser for those younger with healthy gums
I bought this WaterPik 3100 water flosser for a couple of reasons: the first being WaterPik has always been a trusted brand name in water flossers and second, they were offering a good deal. The water flosser I had been using for almost 3 years (another brand) was showing signs that it may stop working. So, I decided to give this WaterPik a try and I wanted so badly for it to work for me. I'll start with the positives: 1. It cleans really well. 2. It has good battery life. 3. I like the design of the water tank in that the hatch for adding water is placed higher up on the tank so there seemed to be less leaking. 4. It is pretty quiet 5. It seems easy to use. However, after a few weeks of use, I decided this water flosser should not be used by older people with sensitive gums because use of it was causing more issues than help. The spray is pretty powerful and perhaps a bit too powerful for sensitive gums. It would be great for someone younger with healthy gums. So if you're in that category this flosser might be a really good option for you. Another issue I had was that the water tank doesn't hold as much water as my other flosser making it inconvenient to keep filling it. I did give this flosser a try and a chance but it looks like I'll be going back to my other flosser.

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.
