Works well and easy to use!! I like that it has many different attachments and the settings are easy to use. Love the product and the price!!!! The water pressure that this has, has impressed me. I am glad that I made this purchase.

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!

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.

I use this Coslus dental flosser regularly and it really cleans your teeth. It has several different modes and works very well. I definitely recommend this flosser. Also a good price for the quality of the item.
