Great Portable Water Flosser: Powerful and Travel-Friendly
I’ve been using the COSLUS Water Dental Flosser for a few weeks now, and I’m really impressed with its performance. The water pressure is strong enough to thoroughly clean between my teeth and along the gum line, yet gentle when using the lower settings. My mouth feels noticeably cleaner after each use compared to regular string floss. The 300ML water tank is a great size; it holds enough water for a full cleaning without needing constant refills. I also love that it’s cordless and rechargeable, making it perfect for travel or small bathrooms. The battery life is excellent; one charge lasts me well over a week of daily use. Another big plus is the IPX7 waterproof design. I can safely use it in the shower without worrying about water damage. The unit feels sturdy, well-built, and easy to handle. Overall, this is a great value for the price. If you’re looking for an effective, portable, and easy-to-use water flosser, I highly recommend.

Incredible All-Around Flosser
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!

New staple in my dental routine
First time using a water flosser and its a game changer. My gum health declined during pregnancy. My dentist reccomended to start using a water flosser. During postpartum I could not be bothered with doing research on the best one and just opted to purchase the lowest priced one. I guess I got lucky because I have no complaints. Its easy to use and gets the job done. I like to use it after every meal. At night I manually floss in addition to using this. If you have never used a water flosser before follow the instructions and use the soft mode until you are comfortable to go to clean mode.

Absolutely LOVE this thing!
I love this water flosser! I have extremely tight teeth and flossing is such a pain and I never feel like I get all the gunk out. I can floss twice a day and still manage to floss something out that smells like death. I am in the middle of a cross country move and my tabletop water flosser is packed up in storage somewhere and I decided I couldn't live without one any longer so I ordered this one. I thought it was going to be much smaller and was taken aback when I opened it because it is rather large. I have it sitting next to my 26oz tumbler and a gallon water jug for size reference. It's a good thing that its that large though because it holds the perfect amount of water for me to make two rounds around all of my teeth. On my first use I used the "soft" setting but I put it on the "clean" setting thereafter. Like I said, I have pretty right teeth and it takes a lot of power to get in-between some of them. That might be a little intense for some people with a more sensitive mouth. My gums were bleeding but I did not experience any pain and I'm sure they will toughen up. I haven't had it long enough to know how long the battery will last me, but I will update this review some time in the future to comment on that. I do like that it comes with a tongue cleaning attachment as well. I brush the daylights out of my tongue, cheeks, and the roof of my mouth when I brush my teeth so I will definitely get high mileage out of that attachment! I'm glad that this one has the built in tank and is cordless, the corded tabletop one I have packed up somewhere takes up a lot of space and I'm currently living in a camper so this is absolutely perfect. It has a very small footprint for being as large as it is, and that's a huge plus since I have a microscopic countertop in my bathroom. Overall I think this was very reasonably priced and good quality. There is nothing like having water flossed teeth. My mouth feels so much better! Floss just doesn't cut it for me but this water flosser sure does!

Great water flosser
I bought two of these water flossers for my sons who have braces, and they work wonderfully. Unfortunately, one device stopped working after two months, but the support team was fantastic—they answered my call promptly and sent a replacement since it was still under warranty. Great product and even better support!
