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.

Love This Water Pick!
Love this water pick! Easy to use and very portable. I find it is better than flossing and much more efficient (very powerful spray). It took me a few days to get use to using it and not spraying water everywhere but it was well worth the effort. I highly recommend this product. So far, after five weeks of use, no problems.

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 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.

Great value, works well.
I ended up buying one of this for every member of my family when they went on sale. Great battery life, good sized resevoir, the attachments are easy to install, and it does a great job cleaning. It also survived two airplane trips in my checked bags just fine. The regular strength is strong so start with the soft setting.

A great dental flosser
My dentist recommended that I buy a dental flosser so, as I usually do, I read the reviews on the ones labeled best and decided on this one. I love it for its compactness and the convenience of being able to take it on trips. It is easy to use and has a number of settings and it is rechargeable. The only down side is that it doesn't come with a charging adapter, but any 5V adapter will do.

Handy and effective portable dental flosser!
This water dental flosser is great for cleaning between teeth and along the gumline, especially when I’m on the go. The portable design makes it easy to use while traveling and it feels gentle yet effective. Battery lasts well and it’s simple to refill and clean. Not quite as powerful as a full-size unit, but excellent for daily touch-ups and travel!

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.

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.
