This flosser does a great job. It is easy to hold, and has good power to clean out between tight-fitting teeth. It is easy to fill, empty, and recharge. I thought it would be difficult to use, but it fits my hand just fine and is light when full of water. I still spray water around, but it is so much easier to use than my larger countertop flosser. I am flossing much more often than I did before I bought this item. It holds enough water. My gums feel great, and I haven't even gotten out of child mode yet. I wish I had bought this sooner.

this product is very good. It worked really well on the teeth and on the gums. The only if he comes up with the water chamber is a little small so you have to build a chamber second time sometimes otherwise no great charging is easy and excellent to use and our or at the thing really works and it can be taken with you with a charging cord and your to go for a long period of time it’s very easy to take with you

Works well. I don't know how much of a difference it makes. I use it after every time I brush though because I hate plaque buildup on my teeth. Does not replace actual flossing. So, I brush, then floss, then use this to wash everything away. Seems ok. Don't know if I recommend, but it's a good value for the price. Not too loud, plenty of water capacity and I do like the rechargeable aspect of it. I've had it for about 2 years I think now, so yeah, it's holding up well for something that gets used at least 3 times a day.

Purchased to use in the shower. It is quite powerful and at the highest setting is a bit too much. One setting down works well and it was worth the price. The battery seems to last a considerable time.

I’m really impressed with the COSLUS Water Dental Flosser C20 so far. It came with multiple attachments, including an orthodontic tip (which I love), and a USB charging cable. Just note that it doesn’t include the wall block, but that wasn’t a big deal since I already had one. I had never used a water flosser before, so my first attempt was a little chaotic — I filled it up, turned it on, and accidentally sprayed water all over my bathroom. Lesson learned: definitely keep it in your mouth before turning it on! 😅 Once I figured that out, it worked great. The pressure is very powerful, which makes it feel like it’s doing a really thorough job. The 300 ml tank lasted me about one full use, but it’s super easy to refill and snap back together. The design is sleek, lightweight, and cordless, which will make it perfect for traveling. Since I just started using it, I can’t speak to the battery longevity or long-term durability yet, but based on the power, ease of use, and included attachments, I’m very happy with this purchase so far. Definitely recommend if you’re looking for a strong, portable water flosser!

Product includes a variety of nosles for use, the charging and battery life provide for a week of daily use. The water reservoir is sufficient one flossing. This being the first water-pick appliance I have used, I was pleased with the ease of use and learning process.

At my age, I've had many teeth crowned. Floss is a nightmare in that circumstance, and I've used those little brushes, which can fit into tight spaces. But very recently, I suffered a MAJOR toothache resulting from a tiny bit of food caught between the bottom edge of a crown and the gum, that triggered bad inflammation. Only an epic brushing finally removed the offending, VERY tiny particle. I immediately decided that I should look in to a water flosser. This one was rated highly, and was affordable (many are not). And this thing WORKS! When I've finished with it, it has washed loose myriad tiny particles from between my teeth, and under the edges of crowns. Hopefully, there will be no more recurrence of that horrible, painful experience from a lodged particle next to a gum line. I'm totally happy with this unit!

I bought this on black friday and haven't regretted it (much) since! Pros: 1. Not very bulky, but I feel it does require two hands to hold 2. I never have to refill during use, since the tank is just the right size 3. I'd say the noise level is pretty modest, similar to an electric toothbrush 4. The battery life is incredible! I haven't had to charge it in 2 weeks!! 5. I got a beautiful turquoise color and it looks so pretty sitting on my bathroom countertop, so it's definitely not an eyesore 6. There is definitely a learning curve when trying to figure out how to use it well without making too much of a mess (I always make a mess, though!) This is my first water flosser and it only took about 2 days to figure out how to use it, but I soaked my mirror, walls, countertops, clothes, and floor during the process, so have towels on hand while you're still learning lol!! 7. It took me a few days to adjust to the water pressure since I have incredibly sensitive gums as well as some pretty bad gingivitis. I have bled maybe once since the 2 weeks I've had this flosser, but my gums would feel sore and achy after every use. That took a while to go away. 8. I love that it comes with a tongue scraper nozzle!! I feel like it really helps with bad breath! 9. I also like how it comes with so many different types of nozzles for everyone's different needs. I just use the standard and tongue scraper, but it also has a second standard nozzle tip, which is pretty cool. You have to replace tips every 2-3 months anyways, so with the two standard tips they supply, you won't have to buy replacements for 6 months!! Cons: NUMBER ONE: THE BIGGEST CON-The charger port is covered by a tiny rubber stopper that you have to take off in order to charge the device. DO NOT LOSE THIS RUBBER STOPPER!!! The very FIRST day I got this, I lost it for about 30 mins and there is no replacement for it. You can't have water get into the charging port or else it won't work, so you really cannot lose this stopper or else you'll have to replace the whole flosser!! They should've made it like the flapper on the tank that is still connected when you take it off to pour water into the reservoir. Trying to keep track of this tiny stopper is a wayyy more stressful than it should be! Lol 2. When you use the flosser, it gets all slippery with water running down the body of it, so make sure you have a good grip! That's why I use it with two hands, so that I'm extra careful to not drop it. Also, try not to accidentally press the buttons during use. Not fun lol! 3. The water reservoir for this flosser doesn't dry between uses, which makes me anxious that it could start to grow water mold. I always leave the flap open to try and help it airdry, but it is still always wet the next day. I haven't had any issues yet with bacteria overgrowth, but I wish there was a way to open it up and dry it. Overall: I'd give this an 8.5/10! For a first time water flosser user, I feel very lucky that this was my first experience! I'm unsure of how well it cleans my teeth, though, so I'll have to check with my dentist during my next appointment to see if there's any improvements. And that little stopper for the charger port brings this rating down 1 whole point because of the mini heart attacks it's given me!! But the ease of use, battery life, color, power, noise, and water pressure are all way beyond my expectations and are truly a treat for your teeth and gums! And the tank not drying or being able to be dried between uses brings the rating down another 0.5 point. But otherwise, this is a really high quality product! It's got a good price and not too many downsides, so I would cautiously recommend to friends if they had a good memory and could keep track of things. But for fellow ADHD folks, this may not be the best, simply because I don't think you can have that stopper replaced or purchase a replica of it. You may have to buy the whole flosser again or just go with a different one that doesn't have such a tiny part you have to keep track of!
