Great Portable Water Flosser: Powerful and Travel-Friendly
I’ve been using the COSLUS Water Dental Flosser for a few weeks now, and I’m really impressed with its performance. The water pressure is strong enough to thoroughly clean between my teeth and along the gum line, yet gentle when using the lower settings. My mouth feels noticeably cleaner after each use compared to regular string floss. The 300ML water tank is a great size; it holds enough water for a full cleaning without needing constant refills. I also love that it’s cordless and rechargeable, making it perfect for travel or small bathrooms. The battery life is excellent; one charge lasts me well over a week of daily use. Another big plus is the IPX7 waterproof design. I can safely use it in the shower without worrying about water damage. The unit feels sturdy, well-built, and easy to handle. Overall, this is a great value for the price. If you’re looking for an effective, portable, and easy-to-use water flosser, I highly recommend.

Good unit, easy to use and seems effective!
The device is very easy to operate. I fill the reservoir twice. Once for the bottoms and once for the tops. I have been using it on the children's mode to get my gums accustomed to the process. It's very easy to change modes. I remove the wand from the unit after I use it. One of the reviews I had read said someone had knocked his unit off the counter and the wand had broken off when It fell. The unit operates quietly and is easy to fill. I dry it off after use and leave the fill plug open and separate the unit to hasten the drying process. I am pleased with the product. It was an easy process to register the unit for the 2yr guarantee. The unit was very easy to charge.

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!

Very durable
I have been using this product for months now, on daily basis, 3 times a day. It works like magic. The charge last for weeks and it doesn’t leak or whatsoever. It is not loud but not very quiet as well. Very comfortable to the sensitive gum or teeth hence it has levels for its tensity. It is worth the month and works great for those who wear braces because it cleans the teeth pretty well.

The best tooth/gum cleaner ever
Love love love it I couldn’t believe how well this water pick works. I was about to buy one from the dentist cause she recommended it to me but after hearing that it was $115 I was like well I don’t need it that bad. Anyways I look on Amazon and I got this bad boy for like $25 and it works really good. If you want the cleanest gums and teeth you’ve ever had (aside for when you get a cleaning at the dentist) buy one of these affordable water picks

Great overall product!
Great product! Have been using this for years now. Have one for me, one for my wife, my niece wanted one so got her one too. Could be a bit more flexible in terms of intensity, but the different modes are nice and I like the more intense mode. Helps keep gums clean and healthy, gets stuff from between teeth easily, and not too noisy. Reservoir is the right size for one person to do both top and bottom, inside and out. Battery life is also very good. Seems like months between charges, although I haven’t actually measured it.

Just add water
Was recommended by my dental hygienist to stop using dental picks and use a water flosser. I never used one before but after watching videos on YouTube I decided to try it. I’m pleasantly impressed and glad I got it. It comes with all you need except for the water. It is very easy to use and works well. It has different settings and is recommended to start out with the lowest setting which works good as well. It has two places to fill with water and has a usb charger cord but not the charger block to plug it in.

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.
