Great value and very easy to use/clean! 10/10.
I'm very happy with this water flosser. The quality-to-price ratio is excellent, especially if you catch it on sale. It performs just as well as more expensive brands. ​Why I like it: ​User Friendly: It’s very intuitive to use, and the different modes (especially the Child/Soft modes) are perfect for getting started without irritation. ​Easy Maintenance: It is surprisingly easy to clean. The water tank is detachable, which makes it simple to dry out and prevent any buildup. ​Performance: It cleans deeply and leaves your mouth feeling fresh from the first use. ​Verdict: Highly recommended for anyone looking for an effective and easy-to-maintain dental tool without spending a fortune.

    A worthwhile alternative to more expensive brands

    Full content visible, double tap to read brief content.

    I purchased this water flosser because it was available at a discount. I was initially unsure about its performance, as Waterpik is generally considered the leading brand in this category. However, after using this product for about 3 weeks, I can say that it has fully met my expectations.

    The unit is easy to charge and convenient to use as a cordless device. So far, I have not experienced any water leakage, and the noise level is reasonable. It is not particularly quiet, but it is not excessively loud either.

    While it is still too early for me to comment on long-term durability, the overall performance has been excellent. The water pressure is strong, and the flossing effectiveness is comparable to what I was looking for in a quality water flosser. Based on my experience so far, I would highly recommend this product to anyone considering alternatives to Waterpik. Brand recognition alone should not discourage you from giving this option a try.

    Lightweight, easy to handle and with a generously-sized water tank, this flosser works very well. It has adjustable settings for the strength of the stream that suits a wide variety of users. Comes with an array of useful attachments. Even when used daily, it doesn't need to be recharged often. Price is a great value. Excellent buy, would purchase again.

    Very good product, excellent for cleaning and massaging teeth and gum. I was a bit disappointed that the plastic closure cap on the bottom broke off after just one week of use. It still functions when attached, but Im fearful I will lose the piece and have no way to close and secure the water/fluid in the unit.

    I love this flosser. It holds the charge very well. This flosser has a variety of settings so you can start light and the pressure can be set to a harder level when you’re ready for it. I haven’t used a flosser in a while, so I started on the child setting so my gums didn’t bleed. Comes with several attachments to fine tune your cleaning. Easy to fill and it is quiet. Easy to pack for vacation.

    I am incredibly impressed with the COSLUS C20. The 300ML water tank is the perfect size because it holds enough water to clean my entire mouth in one go without constant refills. I love that it is ADA Accepted, which gave me peace of mind about its safety and effectiveness.The dual-stream pulse technology works wonders at blasting away food particles and plaque, yet the "Soft" mode is gentle enough for my sensitive gums. Battery life is phenomenal—I’ve been using it daily for weeks on a single charge. It’s also completely waterproof, so I just use it in the shower to avoid any splashing on the bathroom mirror. Highly recommend! This is my second one.

    ​User Friendly: It’s very intuitive to use, and the different modes (especially the Child/Soft modes) are perfect for getting started without irritation.

    ​Easy Maintenance: It is surprisingly easy to clean. The water tank is detachable, which makes it simple to dry out and prevent any buildup.

    ​Performance: It cleans deeply and leaves your mouth feeling fresh from the first use.

    ​Verdict: Highly recommended for anyone looking for an effective and easy-to-maintain dental tool without spending a fortune.

    Incredible All-Around Flosser

    I bought this on black friday and haven't regretted it (much) since!

    Pros:

    1. Not very bulky, but I feel it does require two hands to hold

    2. I never have to refill during use, since the tank is just the right size

    3. I'd say the noise level is pretty modest, similar to an electric toothbrush

    4. The battery life is incredible! I haven't had to charge it in 2 weeks!!

    5. I got a beautiful turquoise color and it looks so pretty sitting on my bathroom countertop, so it's definitely not an eyesore

    6. There is definitely a learning curve when trying to figure out how to use it well without making too much of a mess (I always make a mess, though!) This is my first water flosser and it only took about 2 days to figure out how to use it, but I soaked my mirror, walls, countertops, clothes, and floor during the process, so have towels on hand while you're still learning lol!!

    7. It took me a few days to adjust to the water pressure since I have incredibly sensitive gums as well as some pretty bad gingivitis. I have bled maybe once since the 2 weeks I've had this flosser, but my gums would feel sore and achy after every use. That took a while to go away.

    8. I love that it comes with a tongue scraper nozzle!! I feel like it really helps with bad breath!

    9. I also like how it comes with so many different types of nozzles for everyone's different needs. I just use the standard and tongue scraper, but it also has a second standard nozzle tip, which is pretty cool. You have to replace tips every 2-3 months anyways, so with the two standard tips they supply, you won't have to buy replacements for 6 months!!

    Cons:

    NUMBER ONE: THE BIGGEST CON-The charger port is covered by a tiny rubber stopper that you have to take off in order to charge the device. DO NOT LOSE THIS RUBBER STOPPER!!! The very FIRST day I got this, I lost it for about 30 mins and there is no replacement for it. You can't have water get into the charging port or else it won't work, so you really cannot lose this stopper or else you'll have to replace the whole flosser!! They should've made it like the flapper on the tank that is still connected when you take it off to pour water into the reservoir. Trying to keep track of this tiny stopper is a wayyy more stressful than it should be! Lol

    2. When you use the flosser, it gets all slippery with water running down the body of it, so make sure you have a good grip! That's why I use it with two hands, so that I'm extra careful to not drop it. Also, try not to accidentally press the buttons during use. Not fun lol!

    3. The water reservoir for this flosser doesn't dry between uses, which makes me anxious that it could start to grow water mold. I always leave the flap open to try and help it airdry, but it is still always wet the next day. I haven't had any issues yet with bacteria overgrowth, but I wish there was a way to open it up and dry it.

    Overall: I'd give this an 8.5/10! For a first time water flosser user, I feel very lucky that this was my first experience! I'm unsure of how well it cleans my teeth, though, so I'll have to check with my dentist during my next appointment to see if there's any improvements. And that little stopper for the charger port brings this rating down 1 whole point because of the mini heart attacks it's given me!! But the ease of use, battery life, color, power, noise, and water pressure are all way beyond my expectations and are truly a treat for your teeth and gums! And the tank not drying or being able to be dried between uses brings the rating down another 0.5 point. But otherwise, this is a really high quality product! It's got a good price and not too many downsides, so I would cautiously recommend to friends if they had a good memory and could keep track of things. But for fellow ADHD folks, this may not be the best, simply because I don't think you can have that stopper replaced or purchase a replica of it. You may have to buy the whole flosser again or just go with a different one that doesn't have such a tiny part you have to keep track of!

    Works amazing. I honestly didn't think it would be all that strong from the video reviews I seen. But after giving it a try I'm blown away. It's extremely powerful (in a good way) even on the lowest setting. I turned it on and immediately my gums felt cleaner. A powerful stream of water hit my teeth and it felt like it was deep cleaning. Almost felt like going to the dentist. The grip is very comfortable in hand. I couldn't recommend it any more. The downside is it can get a little messy. Just keep your mouth closed or slightly open to prevent water from shooting everywhere.

    Lo compre para facilitar la limpieza con brackets, ya que con los cepillos de dientes no se hace al 100, ahora con este aparato la limpieza es más fácil y también hace la limpieza entre los dientes y encías

    Pd: tiene 2 años de garantía con la empresa, solo hay que seguir las instrucciones

    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.
