Great Water Flosser for Everyday Use
I’m really impressed with the COSLUS ADA Accepted C20 Water Dental Flosser. It’s easy to use, has great water pressure, and makes cleaning between my teeth and along the gumline quick and effective. I also like that it’s easy to refill and doesn’t take up much space. Overall, it’s a great addition to my daily oral-care routine and definitely worth it.

Seven Years Later, I’d Still Buy It Again
I bought this portable water flosser about seven years ago, and I’m actually ordering another one because it has served me so well. It’s still working, but the rechargeable battery doesn’t hold a charge like it used to, which is understandable after years of use. If you’re comparing it to a countertop electric water flosser, the countertop model definitely has stronger water pressure. But that’s not really the point of this product. This one is designed for travel, and that’s where it shines. It takes up very little room in a suitcase, making it perfect for vacations or international trips when you don’t want to pack a bulky countertop unit. The water reservoir is smaller, so you may need to refill it during use, but that’s a reasonable tradeoff for its compact size. It also comes with several interchangeable tips, which is a nice bonus. One tip: keep the charging cable with the flosser. With so many USB cables lying around these days, it’s easy to misplace the one that comes with it. After seven years of dependable service, I have no hesitation buying another one. If you need a compact, travel-friendly water flosser, I think this is an excellent choice.

I love it
I’ve used this everyday since I got it (it’s been almost 2 months) and I have yet to charge it. It works amazing and makes your mouth feel so clean afterwards. 10/10 recommend.

I found the child setting worked best for me as higher modes as to much power. But do like it.
I use on child as has a lot of power. And found easy to use leaning over sink. And just let water run out if mouth.Easy to fill and use.

This is a good, inexpensive water flosser
So far I really like it! I’ve had more expensive brands but keep knocking them off my sink so wanted to see if I could find a less expensive brand. I’ve had it for a few weeks and really like the way it works. The flosser settings are good, and I actually like the strength of the spray and am using the highest setting. I’m still finding the right setting for the back of the teeth, because the highest settings are too intense when the spray touches my tongue; but it still does the job on the lowest setting.

Dentist-Approved Results for My Gums
I’ve been really impressed with this water flosser. I visit my dentist every four months because I’ve had issues with gum disease and plaque, and I’ve noticed positive results since adding this to my daily routine. It does a great job cleaning between my teeth and along my gumline, and the 300 mL tank is convenient because I don’t have to keep refilling it. The COSLUS oral irrigator also has ADA acceptance for helping remove plaque and prevent or reduce gingivitis when used as directed.

Cleans nicely.
I read reviews saying awkward to hold and heavy and a wee too strong. I don't think it is that awkward or heavy though, I may miss the button to turn it off, but with practice that shouldn't be a big deal. I don't find it a strong stream at all. Actually wish it were just a bit stronger. I'm using the peridontal bit and maybe that is why, I will try others. Love all the tips and settings. I find it to be better than the last one I had too.

Finally a cordless
I love the idea of this water pic however, even the softest spray setting was really hard on my gums and hurt. But it’s great to use instead of flossing my mouth felt so clean! The size of the water pick was a little hard to hold because it was so wide and kept sliding out of my hand, but otherwise it’s great! The cordless charge lasts a really long time and it is durable so great for traveling

El previo y su función son excelentes
Es un excelente producto, ya que la batería rinde un mes, tiene tres modos de presión de agua, se puede poner agua diluida con algún refrescante bucal, llega hasta donde tú cepillo quizás no llegue.
