Better than floss
Really impressed with this water flosser. It’s very effective and removes food stuck between teeth much better than normal floss, especially in awkward areas. I bought it because I have a cracked filling that’s difficult to repair, and food was constantly getting trapped there which was becoming really irritating. Since using this, it clears everything out properly and leaves my mouth feeling much cleaner and fresher afterwards. Maybe a bit bulky but it holds enough water to do the job without having to refill the container. My teeth genuinely feel cleaner after every use. Easy to use, cordless, and much more comfortable than traditional flossing. Definitely worth buying.

Excellent Water Flosser – Powerful, Convenient and Highly Effective
I’ve been using the COSLUS Cordless Water Dental Flosser for a few weeks now, and I’m genuinely impressed with the results. As someone who has always found traditional flossing a bit time-consuming and awkward, this water flosser has made maintaining my oral hygiene much easier and more effective. The device feels well-made and comfortable to hold, with a lightweight cordless design that makes it easy to use anywhere in the house. The water tank is a good size and provides enough capacity for a thorough clean without needing constant refills. Charging is straightforward, and the battery life has been excellent, lasting a long time between charges even with daily use. What really stands out is the cleaning performance. The water pressure is strong enough to remove food particles and debris from between teeth and around the gumline, yet gentle enough to remain comfortable during use. The different pressure settings are a great feature, allowing you to choose the level that works best for your teeth and gums. After each use, my mouth feels noticeably fresher and cleaner, and it’s helped me reach areas that are difficult to clean with a regular toothbrush alone. I also appreciate the range of nozzle attachments included. They make it easy for different family members to use the device and provide flexibility depending on individual dental needs. The rotating nozzle helps reach every area of the mouth with minimal effort, making the whole process quick and efficient. Another major advantage is how portable the flosser is. The cordless design makes it ideal for travel, holidays, or keeping your dental routine consistent when away from home. Despite its compact size, it delivers performance comparable to much larger countertop models. The build quality, ease of use, and effectiveness have all exceeded my expectations. It has become a regular part of my daily routine, and I’ve noticed a significant improvement in how clean my teeth and gums feel throughout the day. Overall, the COSLUS Cordless Water Dental Flosser is an outstanding product that combines powerful cleaning performance, excellent battery life, user-friendly features, and great portability. It offers fantastic value for money and is a worthwhile investment for anyone looking to improve their oral hygiene routine. ⭐⭐⭐⭐⭐ A high-quality water flosser that delivers professional-feeling results at home. Highly recommended! 🦷✨💧

Great value and powerful, but can be a bit intense for sensitive teeth.
As I was upgrading my oral hygiene routine, the Coslus C20 became my choice. It's really efficient and even more powerful than I expected. Performance Review Water Pressure: Regardless of the level you pick, it's pretty strong. This product cleans teeth thoroughly but requires some getting used to with all its modes. Battery & Portability: So far, I am satisfied with battery capacity, it's not connected to the wall, so it's easily portable. Tank Capacity: It's roomy enough. You won't need to pause flossing because of a lack of water. The problem with some portable devices is their insufficient tank capacity. Warning for People with Sensitive Gums There's one point I should mention. It's really intense despite being advertised as a gentle product. If you have sensitive gums, you should start with the minimum level of pressure. On the contrary, the Soft mode was still too much for me and caused some gum bleeding. Start your flossing with the minimal pressure and slowly adjust it as your gums get used to it. Final Thoughts This device is worth buying because of its efficiency and price. It doesn't cost much compared to popular brands like WaterPik. Be careful with sensitive gums. Otherwise, it gives your mouth that nice dentist cleaning feeling.

Excellent dental flosser
This purchase is a game changer for me. I see my dentist every 3 months for a check up and have always brushed twice a day, but still my gums seem to bleed and I am told off by the dentist for not cleaning them properly and I must floss etc etc. My teeth are close together so conventional flossing is difficult although I give it a go. Anyway, I decided to try a water flosser, based on an article I read in the paper and in fairness my dentist did mention them a few years ago, and what a difference it has made. I chose this one because reviews said it was easy to operate and it is. The reviews said it would hurt intitially and it does The reviews said that the pain goes with regular use and it does. For those new to this purchase, no need to plough through the instruction. Simply fill with water via the transparent little stopper at the bottom. Do not interfere with the long tube inside, there is nothing for you to do with that. Choose which head you want and place it onto the end of the device and off you go. My first experience of using it was laughable, as I kept opening my mouth at the wrong time, and also managed to shoot water in my eye and all over my t shirt but one lives and learns. Following my first use, I could not believe the amount of debris from my teeth left in the sink and it made my gums bleed a lot and it hurt like hell. I persisted and tried it the next day but this time, it hardly hurt at all and the debris was much less. Over a week of using it and my gums are in much better condition and are not bleeding at all and there seems to be hardly any bits of food being stuck (I do love nuts and seeds). My top tip is to enclose you mouth round the device when switched on and keep it closed, spitting out the water when it is switched off. You will easily get the hang of it. The battery lasts for ages so that's very handy too. I will update on here after my next dental appointment and this time, hopefully he will not be trying to persuade me to see the hygienist again ! Excellent value for money and my teeth and gums feel transformed !

It's ok. Recommend a very thin bottle brush to clean the intake hose.
It's pretty good as a starter kit / beginners oral irrigation unit. Battery life seems pretty good. Charging speed is ok (i leave it charging overnight once a week). Pressure is good and strong enough to get between the teeth. Has a few different nozzles, but I've only used the main/normal one so far. The size of the unit takes a bit of getting used to. It needs to remain upright for the water to pump properly and trying to manipulate the nozzle around the mouth/teeth can be a bit tricky. I can appreciate why some units make the tank a remote unit. The only real issue I've had is that the tiny amount of water that remains in the tank hose (after running the unit dry after use) went mouldy. Fortunately, I had a suitable bottle brush to clean it, but not including a suitable bottle brush in the kit is a missed opportunity.

great flosser! would recommend!
LOVE!!! has different pressures that you can choose to suit your preference or build your way up. Teeth feel great and fresh after use. May have to fill up a few water a few times if you are thorough like me but is done with ease and has good amount of water capacity. portable so very easy to use with no wires connected. i prefer to normal flossing as feel like it gets in all the nooks and crannies. had for about 1-2 months and havent had to charge once yet so has great battery life and seems sturdy. comes with many adaptions which are very handy. button responsiveness is great so be careful not to accidentaly press and spray walls as have done a few times aha.

Hard to master..but definitely worth persevering 🤣😊
I purchased this water dental flosser after my dentist said my flossing between a new crown was not that great 🙄 I was using the teepee interdental brushes but it was obviously not doing an adequate job! I read about the water dental flosser saw it was on a good offer on Amazon so thought ideal..give it a try. I have to be honest the first use I ended up with water all over my clothes ,hair & bathroom! I did read in the instructions you should leave mouth open slightly whilst using...but resulted in water running everywhere. I discarded it for a few days...thinking...waste of money. However I had another attempt & this time gently closed my mouth around the jet tip..blast for a few seconds..turn off spit out water & repeat...this actually worked😊 ..I had a few mishaps but ..getting better every day 🤣 I am so glad I persevered. It actually does an amazing job. I tried a test....I ate some nuts which always seem to find their way between teeth & gums. Firstly I used my interdental brushes..thought I had cleaned sufficiently..but....then used the water flosser....I couldn't believe the amount of food that came out. I then tried the other way round..I ate nuts..used the water flosser first..lots of food came out..then used the brushes...couldn't find any remaining food ! The flosser feels comfortable in the hand the tank when full is enough for a full clean. I used warm water as it felt more comfortable especially on sensitive teeth. Firstly I used the soft setting as advised but have progressed to the clean setting. I really think it makes my teeth feel cleaner 😬...Will update on my dentists opinion in September 😁 I found the bottom water inlet opening a bit fiddly so detach the tank & fill from the top ( personal choice) The charge is via a USB cable..the adaptor is not included but that's no problem as I have many for mobiles & other devices. I like the different settings. Also I charged on receipt & have used twice daily for 12 days.....apparently can last for 30 days...a bit like my toothbrush I guess.. Although 5 jet tips are included I will only use the two standard ones. So after nearly.throwing in the bin..I am so glad I persevered as I am really happy with the results now. Definate 5/5 for the product ( a bad workman blames his tools..so they say 🤣) The dodgy start was more due to me than the product ! I would reccommend ....especially when on offer at such a good price. The product also has a two year guarantee. Update 🥳😁. My dentist commented on the improvement of my cleaning of teeth! Usually I have a scrape & clean but he decided I didn't need it this time !!! Thus saving £75... so the water flosser has saved me money!! By the way..I have really mastered it now🤣...& find it quick & easy to use.

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.

Works great and delivers excellent value
The COSLUS C20 has strong, consistent water pressure, a good‑sized tank, and multiple tips that make it easy to get a deep clean. It feels solid in the hand, the battery lasts a long time, and the whole thing is simple to use and refill. My teeth feel noticeably cleaner after using it, and it’s a big upgrade from regular floss. For the price, this flosser performs way better than expected — definitely recommend it.
