Quality Portable Flosser
This flosser is very effective and easy to use. Excellent quality and every bit as comparable to the brand name product. It is rechargeable, powerful, has different strength settings, and the water reservoir holds a lot of water! Numerous tips are included. It is well built, attractive ,and is marketed at a good price. Great for travel.I am very pleased with this product..

A worthwhile alternative to more expensive brands
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.

Works amazing!
This is 100% worth the price (which is a great one)! It honestly cleans my teeth so quickly and thoroughly! My dentist will be proud and disappointed (no new cavities or plaque build up). Honestly, if you're thinking about buying it, just do it already. It's great quality too!

Cleans great & NOT just mouths, but...
Ok, been looking for cordless water pick (water floss) system for years a not fan of the typical unit that's big taking up counter space by bathroom sink. I have very little space, & need to take when travel, a pain. So I found this and looked great, & when arrived it was packaged nice, new, and build quality is fine, being normal shiny black plastic. Nothing is rough, sharp, smells or tastes funny either. The tank size is 300ml & for cordless that's 10x my cordless I replaced. Can fill tank 2 diff ways. Either w/ convient quick access on side by bottom; yes, gasket included & right firing too & had ZERO LEAKS USING. Other easy is popping tank off pump itself which super easy as slides off/on with satisfying CLICK, so know it's ON. This also makes cleaning VERY EASY INDEED. The auction tube on pump is removable for cleaning as is built in filter. The controls don't stick, reactive when press & unit stops when turned off rather quick, I was impressed actually. Has 4 modes, clean/ normal, soft, child/beginner, massage. Tips, 5 of them (2 normal, 1 tonguecscraper style, 1 soft brustle brush at tio for braces or dental appliances, & 1 fine point targeted tip), are easy to install, rotate 360 & typical size get with units; except the units paying over $300 easy; as do get tips that tend to be"flexible a bit" & not as ridgid as these plastic ones; if did i mention Tips all have GASKETS too and semi-one way Valves w/ 2/5 toe debris filter (non cleanable or replaceable BUT 4 TIPS COST $5-$10; so being aconsumable in cool with that) . Charging port has removable protection Gasket "plug" that's "keyed" (goes in 1 way, like charging cable) & is tight fit. Charging USB-A to proprietary "end plug", wish was usb-c but it works & charges in 5w adapter in 2 hrs when opened mine, but unsure on batt lvl when arrived, so expect all different charging times. Now, if full tank pay max level, unit will "leak" a bit when tilted but that's normal for handheld tank unit cordless or manual pump unit etc. So than why the low score ihave it. PRESSURE. Regardless of mode in in, the Pressure is too strong and is painful to use. B/c of my needs this way to strong it hurts me. Had family member try who owns a $300 waterpik system that takes up size of hand towel and they said was bit strong even in child mode, & no pressures adjustment control to give tune, but that's fine b/c not a $300 unit. I will say b/c of pressure & tips found that using this to CLEAN with works super awesome, & I'm talking cleaning dirty drain stops, small parts from duff tools, bathroom grout & the hard to reach behind bathroom shower/tub sliding door. Also found other uses like cleaving toilet bowl flush holes that get black ya know what mean, this breaks it up. So, for cleaning other things not MY TEERH I give 5/5; BUT IF HAVE SENSITIVE GUMS AND TEETH, BE CAUTIOUS at first. If pressure for child/beginner mode was just 1-2 lvls lower (on scale of 1-10), it would be perfect for me. Am I keeping, YES, b/c getting dental work done to hopefully fix gum/tooth area that's too sensitive & hoping will be fine; besides, have great cordless handheld cleaning spray pump that's priced PERFECTLY!

It works. It really works!!!
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.

Works as advertised - good product - reasonably priced.
Works great - don’t use if you’re dealing with a temporary crown. Yeah, I did that. Charges reasonably fast and stays charged for a long time.

Easy to use and effective flosser
Great tool for dental hygiene and especially helpful for those with braces. Flossers for braces are not easy for all, so this water flosser is easy and effective.

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.

Totalmente complacido
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
