Love it
Have waited a while before positing my review so I can give an honest review. I am so happy with the water flosser. Not only is it affordable it works great for me. It comes with several different pick tips to choose from and you can adjust the setting speed which is key if you need them for implants like me. I had dental implants surgery about 6 months ago and use this at least 2xs a day. The charge stays for a long time, and you have to refill the water tank often depending on how much water you use at a time however that is a good thing because you really don't want water siting in something too long. Fresh water is always better. It is easy to change the picks and refill. Charging is fast and it even comes in a few colors. I got green to match my countertops in my bathroom! Highly recommend!

Great product!
This is a game changer! My dental hygienist recommended a water flosser. I'd only known of the large tank ones. This is portable, holds just the right amount of water for a single flossing, rechargeable, easy to use, effective, and leaves my teeth with that dental clean feeling! I actually look forward to flossing! And I bought 3 as gifts!

Good for the price.
OK, it works. I have braces. I bought this to help keep my teeth clean between cleanings and reduce unwanted plaque. It takes some getting used to, in that the instructions state the best angle for the jet is 90 degrees to the gap between your teeth. You can do that, but you have to practice. Otherwise, the battery life is good, the additional water attachments are helpful, and it's very portable. Having the ability to pack this in a bag is a huge advantage over a more traditional water pick type devise. Good for the price.

Powerful, Adjustable, and Great for Travel
I’ve been using the COSLUS E40 Portable Water Flosser for a short time now, and the performance has been impressive. The 10 pressure settings make it easy to customize depending on sensitivity, especially if you have braces or sensitive gums. Even on the mid-range settings, it provides a strong, steady stream that feels effective at removing debris between teeth. It gives a much cleaner feeling compared to traditional floss alone. The cordless, portable design is a major plus. It’s compact enough for travel and doesn’t take up much counter space. The water tank is easy to fill and clean, and the controls are simple to use. I also appreciate that it’s BPA-free, which adds peace of mind for something used daily. The battery life has been solid so far, lasting multiple uses before needing a recharge.

Great for kids b/c of the varied settings.
I ended up buying one of this for every member of my family when they went on sale. Great battery life, good sized resevoir, the attachments are easy to install, and it does a great job cleaning. It also survived two airplane trips in my checked bags just fine. I had to get this one for my daughter b/c the normal model of this is too strong, so the level 1 or 2 is great for a beginner child with these. No leaks, works great.

Better than Described. Cute and Does Job
Use this everyday. Cleans and alternative to floss. Works great. I clean it regularly to ensure gums feel fresh and teeth clean. Can adjust water flow power for gum type, cordless easy to hold, looks good on counter USB charge charge lasts long had it for awhile and it is holding up.

Great for Gums! Bad Charger System
Review for: COSLUS Portable Water Flosser for Teeth: 10 Pressure Settings Professional Water Dental Pick for Orthodontic, Braces & Sensitive Gums - Cordless for Travel Use, for Adults Teens, BPA-Free, W40(WFP14) Update: After using this device for several months I can say there has been nothing that has helped my gums more than using this water flosser. I have had no problems at all with it, other than the jet being quite strong. My gums are in much better condition now, though the flosser does still sometimes cause a little bleeding. I have not found anything better for cleaning under my bridges, much better than normal floss. I do still use floss every day, and this device every day. I store it on it's side so no issue with water staying inside the control knob. Changed my rating from 3 stars to 5 stars despite the rather stupid charging cord (why not use a normal USB C connector?). Original Review: This thing sure has a powerful water jet! OK, just starting out and using lower power settings. I am finding that the flosser does what it is supposed to do. No issues there. Strong settings do cause some pain, and it is easy for the power dial to be moved to a different setting so be sure to check every time you use the flosser. Strong settings causing pain? Yes indeed! Set to high and pointed at my hand left me wondering if the water jet would break the skin on my hand, it is that strong. Low settings are great though. Maybe after a few months use I can set it higher, or maybe no need... The charger system is not well designed and they take the cheapskate route of not including the actual charger, just a cord. That is what most companies do these days, but what makes this one particularly bad is although the cord requires a USB A power supply, the other end only works with this device. This means you must keep track of yet another charging cable instead of the manufacturer using a standard USB C connector on the flosser. Stars off for the charging system, for sure. Cleaning? Good luck. The (extremely fine print) instructions say to clean and dry the flosser for storage. How on earth are we expected to clean and dry a water tank that only has one 1/2 inch hole for access? Instructions also say to be sure to drain water out of the speed control ever use. I am guessing that there will be some nasty build up in there after a time. Charging port? Instructions say we must not get water in the charging port. Many other devices with USB C connectors are at least somewhat water resistant. Stars off for these things. Overall, the flosser works, cleans my teeth as intended. My gums feel better after using on low power for a week. So, the score is flossing function, 5 stars, everything else is somewhat disappointing. For the price, I am happy enough with this unit. Not sure other, more expensive flossers would be much better, but I have not tried them... If I find issues with this flosser in the future, my review will be updated.
