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.

Perfect Water Flosser
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.

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!

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. โWhy I like it: โUser Friendly: Itโs very intuitive to use, and the different modes (especially the Child/Soft modes) are perfect for getting started without irritation. โEasy Maintenance: It is surprisingly easy to clean. The water tank is detachable, which makes it simple to dry out and prevent any buildup. โPerformance: It cleans deeply and leaves your mouth feeling fresh from the first use. โVerdict: Highly recommended for anyone looking for an effective and easy-to-maintain dental tool without spending a fortune.

Easy to use and effective
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 youโre ready for it. I havenโt used a flosser in a while, so I started on the child setting so my gums didnโt bleed. Comes with several attachments to fine tune your cleaning. Easy to fill and it is quiet. Easy to pack for vacation.

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!

LOVE LOVE LOVE. Itโs effective & powerful, Iโve been using mine for the past 3 days now and have noticed a crazy difference, I donโt have insurance so my main concern was the minor plaque build up I was getting, my first time using it and it took most of the plaque off of my teeth! Iโve even ran a floss between my teeth after using the water flosser and the floss was clean! I 100% recommend this product!
J**.
Highly recommend
This water floss is great. Makes cleaning between my teeth fun. Iโm not sure if itโs as effective as a physical floss scraping the bottom of my gum but it will definitely flush out any bits of food. I used to floss every other day because Iโm lazy like that but using this is so easy that I donโt mind using it every night. Itโs strong enough to get anything out between your teeth and gentle enough not to hurt your gums.
