Great for travel.I am very pleased with this product..

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!

Perfect Purchase
This is a very good item. It really does clean hard to reach areas of your mouth. I am a daily flosser. I tried it on areas that I did not floss and it removed the food very well. It took me a while to aim perfect before getting a slight shower all over my face. I got it down now. I have not charged it in months. Long charging time. Perfect Purchase

It's a nice quality unit, but I'm returning it
This was my first ever water flosser. I'm 73, and have always brushed arduously, multiple times per day. In the last twenty years, I had good dental checkups with rare cavities. The Covid pandemic changed that. Clinics in my area (rural Maine) shut down, and my finances got worse. Result: no check ups for three years (and therefore no dental hygienists) led to seven cavities. Dentist said, paraphrasing, "You're not being effective enough on plaque with just a brush. Get a water pik." So that evening, after reading some basic online reviews and MANY customer reviews on Amazon, I bought this one. Remember, I'm a total newbie to these kinds of tools, and the learning curve is steep, kind of like learning to ride a bike or roller skate. (Expect goofs.) When I received it and unpacked it, I could feel quality (that matches all the Amazon reviews I read). I used it for about ten days. Half way through, my dentist said, "Yes, this is a MAJOR improvement. Keep it up and you won't have problems." Good. But in the last few days, I started understanding why this one -- as quality as it is -- is the wrong tool for me. But being a beginner, I'm still learning how to ride it ... er, use it effectively. I've tried it over the sink -- messy -- and in the shower (before I shower); the latter is less messy, but not convenient for a quick water floss after lunch. I'm finding the learning curve is steeper than expected with this unit ... which IMHO is not a good one for beginners to start with. (It's more of a portable unit for traveling by experienced water flosser users.) Here's why it's not right for me. First, it's larger and heavier than is comfortable (at least for me, an older novice) to manipulate effectively. It contains 300 ml of water, making it heavier (300 ml is approx 0.6 lbs). Second, and worse, there are only three water speeds, and two are not very different. So it's basically fast and faster. For starters, I found the fastest speed to be way too much water; it actually hurt my beginner gums. But even on "soft", it's too fast for me. It doesn't hurt, but it's just too much water too fast. I want to be able to adjust to 3 (of ten) to learn with, then dial up the speed as I get better with it. Third, and probably worst of all, I can't figure out how to hold it securely without pressing the push button controls accidentally. Those controls are on the "back" side of the narrow part, just below the attachment port for the nozzle. When I grip it tight enough to prevent it slipping from my grasp when wet, when I'm trying to aim it properly in my mouth without choking myself or shooting water all over the bathroom, I get a little panicked and press the off switch or accidentally change the speed. (A video of me during one of those times would look like a slapstick comedy routine worthy of The Three Stooges.) So I'm returning this (already printed my return label) and replacing it with a Waterpik electric unit with a hose and speed controls on the main unit, not on the handheld piece. It's costing me roughly $23 more than this ($62 shipped), but for my beginner needs, it'll work better. But again, I want to stress that my issues with this unit have zero to do with quality of functioning or the unit itself. I think for an experienced user who can water floss with a portable unit while making out a grocery list in your mind, this is a fine option. I commend Coslus for producing a quality portable unit for such a low price point. I would have purchased their "desktop" model, but it's outside of my budget.

Great for home use or travel.
I love my plug-in countertop water pik but wanted something that would be easy to take on short trips or (unfortunately) hospital stays. This was perfect for me. It came in a box that I was able to keep as a safe travel container as well as several specialized attachments. To be honest, I didn't use any of the attachments as I use my old stand-by for that, but for routine cleaning this worked great. I loved that I didn't have to pay for batteries or worry about them running low while traveling. Instead, just a short recharge and it was ready to go and lasted a long time. It also has an indicator light to let you know when it needs to be recharged. The noise was about the same as my other pik but nothing too loud. The cleaning was on par with the larger counter-top model I use at home. It seemed a little big and awkward at first, but I adjusted very quickly and it was easy to use and manipulate. It adjusts from gently cleaning - gum massage to "clean the grout" strength. It was also very affordable. Overall, I am very pleased with this purchase.

Add it to your Dental Routine
This is a game changer for cleaning teeth. The charge lasts a long time, it’s durable, and the strength of the flosser is strong but in a way that won’t make your gums bleed. (I mainly use the “soft mode” though) The only issue I’ve had has been bc of myself. lol I have accidentally turned it on without having it in my mouth and have sprayed the mirror and almost ceiling with water. I think if there was a way to lock it in a mode or even to keep it off that would be a cool addition. To switch modes, you can do so without having it on which is nice. Just keep in mind yall still need to floss your teeth with string. This is just additionalan additional tool to help with cleaning. And they give you plenty of flossing attachments to start with. My favorite was the one that was more pointed and a soft tip bc I felt like I could be more accurate and wedge it in between my teeth better. I have also accidentally dropped this from the counter. I snapped off the adjustable tip and I thought it was going to be done. But I was able to get the piece out and it still does on strong. I recommend completely breaking it down after use though to allow it to dry. My apartment has extremely hard water and if it sits, it’ll build up. Thankfully though, this thing is easy to break down and put back together. How I break mine down: Detach the container of water and empty out, pull off white circular plastic piece connected to the end of the clear tube, run the flosser upside down (without the container or bottom plastic circle attachment) to expel any water left inside, detach tube as well as the head of flosser to allow to dry. By the morning it’s good to go

Love this dental flosser!
I really like this dental flosser. Very reasonably priced, you get 2 of them and it holds a lot of water. It is easy to use, charged and ready to go.

Great Dental Flosser
I always find it difficult to use the string type of Dental Flosser as my teeth are too close together and it bleeds when I forced the string between the teeth. With a Water Dental Flosser, I don't have any problem as the water jet is strong enough to flush in between the teeth. I need to do this as my gums are quite sensitive and get inflamed if food are stuck in between the teeth which toothbrushes cannot get it out.

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
