We have been using Coslus for over 18 months and it has been a game changer. We got a third Coslus (their latest one) provided by the company in exchange for an honest review. We have only used Coslus branded waterpik but find no reason to switch to any other brand. It is convenient, holds the charge quite well and does an excellent job of cleaning. I highly recommend it to anyone looking for a waterpik. Their customer service is top notch too. Thanks Vic
charge little extra and include a storage bag would be a plus, not only will keep far better looking, but also be great for travel or keep parts in one place. i will go buy a bag, but i expected to come with when i bought my other one did and was cheaper only thing with this one is the tank (bigger)
It cleaned my teeth pretty well, definitely better than my old one.
works great!
works great and I like the bigger water receptacle
Love it
I really like the product. I placed Isopropol alcohol in the reservoir to sterilize it, but the alcohol destroyed the water reservoir. I wanted to purchase just the reservoir, but was not available. I was required to buy a new unit.
Works surprisingly well. Easy to operate! Glad I purchased it. Thanks!
I recd the flosser, but no attachments. Will they come separately?
We have started offering this waterflosser to our patients. The ease of use, variety of tips and large reservoir are some of our favorite features. As a dental hygienist, I love being able to offer our patients an affordable and effective way to improve their oral health.
Looks like the brand name water flosser only without the brand name. It's amazing how many little specs of food this device can flush from between my teeth. I use it morning and night, only takes a couple of minutes, then brush as usual with my electric toothbrush. I was getting a lot of staining and buildup between dentist visits. This has cut that down dramatically. Caution: Keep your mouth closed until you hit the Off button if you don't want water all over the bathroom and you - lol.
Itās very powerful. I feel my whole mouth is really clean afterwards in between teeth and bridges! I do not care for the rotation of the tip. It moves if you bump it up against a tooth, it can go sideways. Other than that, I love it.
This is a replacement for a dental irrigation system that finally died after about 10 years. I like the new one mostly. It is powerful and certainly cleans my teeth well. It charges quickly and remains charged for several uses. My only quibble is the shape of the water reservoir. The narrow part is hard to clean and Iām worried it might get mold in it after repeated use.
I have it as a gift but hopefully it will work fine

It's very powerful.
I was hesitant to use one but after using this water flosser it is a game changer. Definitely helps people with caps and crowns.
I love it makes my teeth feel 1000x cleaner and now i am more confident about my smile!
First use of this was hysterical I cleaned behind me the roof the mirror and got a free shower and hair wash that also included my partner who came to assist after hearing my shreiks and laughter Top tip do not switch on if not in your mouth or switch off before renoving from mouth sounds easy and common sense but definitely a challenge as you do not expect the water to come at you so fast ! I couldn't read instructions too small and the leaflet got soaked a waterproof leaflet identifying the nozzles and what settings do use with each one would have helped as I still don't know bar the tongue cleaner which I am definitely not using again as that was just weird Maybe because my tongue was clean ? But saw nothing Definitely with random trials I can now get food out that regularly gets stuck in a certain tooth so no more pulling faces all night doing tongue Olympics Worth a try but try naked and use warm water !
Love the large tank and the powerful sprayer Iām sold
This was my first time using a water flosser and I am super impressed with this unit. The product is exactly as depicted and I have already achieved great results. My gums are fantastic, my teeth are whitening more every day, and my mouth feels better than dentist clean. This has replaced my semiannual dental cleaning because it does a better job (every day)! This is my favourite part of my morning routine and I couldnāt be happier! Thank you!
Super high pressure and high quality! Compared to other cheaper water flossers online this one is far better. Has a hole on the bottom of the water chamber for easy filling and charges pretty quick. The 3 settings are useful for increasing / decreasing the pressure but i always keep it on max pressure - highly recommend
Very good and fun
This has made a huge difference to the cleanliness and hygiene of my mouth. Teeth, tongue and gums all far cleaner and feel better!
Very powerful
During a move I have missed placed my first one. I liked it as good if not better than my sonicare.
Recently I had a new crown and an implant done and I was recommended to use a liquid floss by my dentist as I was getting constantly annoyed by food debris getting stuck between the teeth. The standard waxed dental floss and dental harp floss were damaging my gum with constant use. Coslus Oral Irrigator however was clearing these food debris quickly and gently. It takes a little practice using it without spilling or spraying the water all over near you. I refill the water daily as I use it regularly after eating. I wish I had bought this a long time ago. I am now planning to buy another one for my partner.
Love this
I recently got braces and this has been so helpful in getting all the food out after meals. There are different heads so you can adjust the strength. It achieves quite high pressure cleaning! Only downside is that it is quite big, so a bit of a hassle to take with you on trips.
Isnāt there a warranty to exercise? I was changing the adapter and it snapped, havenāt even used the product long and love it the few times I got to use it, so I donāt want to purchase another one. Just need the product fixed.
Excellent product and excellent customer service.
Got it, love it and not only love itā¦.addicted to it especially after I eat.
Battery was good right out of the box. Nice power and the water tank lasts for a while, unlike last unit I had from another brand. The head does seem to spin around during use, which makes it challenging to get between each of my teeth. I imagine a little practice can't hurt. All in all, a good purchase I am happy with.
Just got mine canāt wait to use it!
