ADA Accepted E40 Water Dental Flosser, 10 Pressure Levels, Black Pro

This cordless water flosser has completely upgraded my oral care routine. I’ve used several water flossers over the years, and this one easily stands out for its power, flexibility, and thoughtful design. The 10 pressure settings are a game changer. The stepless dial is incredibly intuitive—just like adjusting the volume on your phone—so you can fine-tune the pressure in real time with one hand. I have sensitive gums, and being able to start low and gradually increase makes flossing comfortable instead of painful. It’s perfect for everyone in the family, including kids, adults, and anyone with braces or dental work. You can tell this product was carefully engineered. The dual-flow technology provides strong, even cleaning that reaches between teeth and along the gumline, removing buildup I didn’t even realize was there. The materials feel solid and high quality, and I appreciate that it’s made from BPA-free, safety-certified components. It’s also excellent for travel. The compact cordless design fits easily in a bag, and the battery life is impressive—I only have to charge it about once a month with regular use. The USB charging makes it super convenient anywhere. The customizable nozzle system is another huge plus. The included tips (standard, orthodontic, and periodontal) make it easy to tailor the cleaning to your needs, and the large 300ML water tank lets me floss my entire mouth without stopping to refill. It’s great for multi-user households too. Finally, the IPX7 waterproof design means I can use it in the shower without worry. The motor is powerful yet smooth, delivering consistent water flow without splashing or discomfort. It feels durable and built to last. Overall, this water flosser delivers professional-level cleaning in a portable, easy-to-use device. If you’re serious about improving your dental hygiene or want a convenient alternative to string floss, this is an outstanding choice. Highly recommend!

I purchased this COSLUS ADA Accepted E40 Water Dental Flosser for my home, and it has been an excellent addition to my oral care routine. I have always wanted a more effective and convenient way to keep my teeth and gums clean, and this water flosser has exceeded my expectations. The 10 pressure levels make it easy to customize the intensity based on comfort, and the different settings are helpful for everyday cleaning. It is simple to use, powerful enough to remove food particles, and much easier than traditional flossing. I love that I can use it at home as part of my daily dental care routine, and it has helped me feel more confident about maintaining good oral hygiene. The design is practical, the water tank is convenient, and the device feels well made. Overall, this is a great investment for anyone looking for an easy, effective, and comfortable way to support healthier teeth and gums.

I bought the COSLUS ADA Accepted E40 Water Flosser about a year ago and after a year of consistent use, I can confidently say that this water flosser has far exceeded my expectations. The many different tips make it very versatile and great for orthodontic work if needed. the size makes it easily portable and the tank is easy to refill. My only complaint is that the openings of the tank are small so I cannot get in to clean it as well as I'd like. The different settings are great on the tender spots that need a bit more care and it seems to have held up well over the year I've had it. Durable, gentle, easy to use... definitely worth the price.

I bought this for my mother. She enjoys it and loves the variable levels of it. Its not too terribly heavy. She is able to hold it for as long as it takes to clean and it doesnt hurt to hold it long term. She had arthritis and holding things can also be problematic. The price is truly reasonable considering that its portable and adjustable. It is powered by internal batteries. It is easy to refill and easy to charge since it is rechargeable. So no cables while you use it. It hold enough water for an entire session.

This is an excellent choice for a water flosser. It isn’t too bulky and has an ample water container. Comes with two regular attachments, an ortho attachment and a tongue cleaner. With ten settings, it’s easy to find one that fits your needs. I also purchased the C51 primarily because of the easy to clean water dispenser. Equally as nice as the E40 but has only six settings as opposed to ten. I think it’s important to not that the C51 is much easier to clean and that was a big issue for me. In order to prevent mold, being able to fully dry the C51 is a definite plus. In addition, the C51 has the ability to store the flosser attachments inside the base. This is a brilliant design and was a game changer for me. I highly recommend both units based on your needs.

SORRY SORRY SORRY! A TERRIBLE MISTAKE I MUST CORRECT—I DISCOVERED WHEN I CHARGED MY WIFE’S E40 THAT I PLUGED INTO THE WRONG CHARGER. IN OTHER WORDS, MY WIFE AND MY E40 STILL WORKS AND WORKS WELL. SORRY FOR THIS MISTAKE AND LOW REVIEW. COSLUS IS A RELIABLE/DURABLE UNITE! BEFORE I DISCOVERED MY MISTAKE, I DID ORDER ANOTHER COSLUS E50. NOW I HAVE A UNITE IN RESERVE. The new E50 comes with a 2 year warranty which is unheard of regarding water piks. The Coslus ADA lasted for less than 9 months. Worked great for that period of time, but now it will not charge. It appears to be made well, and the charge lasted for months. The price was also acceptable. I guess for $20 one cannot expect longevity. I may reorder The Coslus, but I will also look at similar products. My wife has the identical E40 and it is still working. However, I have just put it on the charger hoping it will charge.

Excellent when it was running. But 1 year and perhaps 2 weeks after purchase the battery is lasting only a total of 1 day (used 2x a day). I'm hesitant to purchase another one at $40 for it to die again in a year. Disappointed with the break down because it was excellent when it was working properly.

Great for travel, great ease of use and good water pressure for a cordless water flosser. I was pleasantly surprised!

Muy bueno precio calidad
