Super Flosser.
This water flosser is easy to use the water tank holds enough water to get the job done and leaves your teeth feeling really clean and fresh, the item is designed very well and is comfortable to hold, the only downside is the filler cap on the water tank is a little bit flimsy so you need to be careful when filling it but you can remove the tank and fill it from the top instead, the charging time is good and lasts very well between charges. It is good value for money and i am really glad i purchased this flosser and it looks nice and comes with a good supply of accessories. 10/10.

Best Flosser Ever. A True Bargain.
I’d give this item 10 stars if I could. Very large reservoir. Only need to refill once when doing the whole mouth. And that’s at a relaxed pace. It’s very powerful and easy to adjust the 10 different levels by way of one handed operated dial. Battery lasts for weeks before the rechargeable battery needs recharging. Has several different heads. Has a massager function. I’ve owned 3 or 4 different water flossers and this blows the others out the water. Good pulsing flow to dislodge food particles. Not a constant, less effective flow like some. Believe me. It is fantastic. Better than ones that cost 4 times as much! Buy one.

It took a little getting used to. The more intense settings were too much for me but the gentler settings seem OK. Did ask my hygienist about them. She said they are worth using along side other treatments as they force oxygen into gum areas. Support from the seller was excellent.

Excellent product.
I bought the 2025 water flosser model which I think is great. I’m happy with this water flosser. This is the first water flosser I have purchased. Took a couple of times to get used to it but now find it simple to use. I have been flossing for a long time using different methods, this is the easiest method. I use slightly warm water as that is the most comfortable for me. My teeth and mouth feel cleaner and fresher. I even checked with my usual flosser after using this water flosser, there wasn’t any debris within my teeth at all. This isn’t any noisier than my rechargeable toothbrush. The attachments fasten securely. Two years guarantee is also useful. This is the second item from COSLUS I have purchased through Amazon.

BEST WATER FLOSSER I HAVE EVER HAD
I don’t usually leave reviews, but I had to for this one. This is by far the best water flosser I’ve ever owned. I’ve gone through at least three different ones in the past year, and they all had the same issues — not strong enough, poor battery life, or they just randomly stopped working after a couple of months. I decided to give this one a try because of the 10 different pressure levels, and let me tell you — it did not disappoint. It’s actually powerful. I’ve been using it on level 7, and even that’s stronger than the highest setting on any of my old flossers. Battery life is also amazing. I can go two weeks (sometimes more) without charging, and it still works just as well as day one. Honestly, I’m super happy with this purchase. If you’re in the market for a good water flosser, this is the one. It’s even better than some of the pricey ones out there.

It was great for a few months.
Really good water flosser! To start with it was really powerful! Good constant water jet for flossing. I have found over the past couple of months tho that this does seem to be losing its pressure. Even on the highest setting it still nowhere near as strong as it used to be. Shame really as the design and the idea behind it is really good. Battery life is great, don’t have to charge it all that often. If it was still as powerful as it used to be, it would be the perfect water flosser! Maybe I just got a faulty one?

Should have bought one sooner!
Should have bought one sooner! I used to get a regular toothache from certain vegetables getting stuck in my teeth in an unreachable place in the corner of my mouth, but no longer! This powerful device spares me of all dental pain as it blasts all food out from the deepest and darkest crevices! It has an adjustable dial for the strength of the water which I massively appreciate! It also looks cool and has a long battery life! Fantastic value for money.

Needs a couple of tweaks.
Good water flosser, used mine on full setting which worked well. Good size water tank, saves refilling half way through. Needs a couple of tweaks to make it 5 stars. The charging port would be much improved by changing it to USBC. The filling door should be redesigned, to one that is easily removed. I’ve managed to break two by flosser falling in sink when draining. Should be made similar to other makes, whereby the filling door just pops out and can easily be re-attached. The hinge design on this is too weak, and easily breaks.

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!

I’ve been really impressed with this water flosser. The power is strong and effective, yet it’s still comfortable to use. I love that it’s rechargeable, and the battery lasts a long time between charges. It also comes with several accessories, which makes it versatile for different needs. The adjustable settings are very convenient, and the size is practical—not too bulky, so it fits easily in the bathroom. One thing to note: there’s a little learning curve at the beginning—expect some splashes until you get used to it! 😅 But once you do, it works great. Overall, a reliable and efficient tool for oral care. I definitely recommend it!

This has several attachments, which I have not used all of them yet. I have sensitive teeth and gums and since using this I find my teeth and gums have improved, I am very happy with it.
