COSLUS Water Dental Flosser Pick for Teeth: 4 Modes Cordless Portable 300ML Larger Tank Water Teeth Cleaner IPX7 Waterproof Flossing Cleaning Picks for Home Travel Black C30(FC5360)Global Recycled StandardGlobal Recycled StandardGlobal Recycled Standard

I bought this for my daughter as her orthodontist recommended, she absolutely love this water flosser. It’s compact, powerful, and super easy to use. The different modes make it great for sensitive gums, and it really helps clean around her braces. I highly recommend getting this as it is a good value for the price and it does the job well.

I had my last sonicare water flosser for barely over 1 year & it stopped working (all the lights came on when charging, but nothing would work. I can only guess it wasn't as water resistant as they claim. Water runs down my arm as i use them, but never got it more wet than what would get on it that way, & i always kept the rubber cover over the charge port). I didn't want to spend $80 on another name brand water flosser that may not last. So, i decided to try a less expensive brand. It works just as well, the attachments i had left from my sonicare flossers actually fit this one, too.The one thing i hate about these is the power button placement. It needs a switch, not a button, in my opinion. It's not a knock against this brand, because they all are in a horrible place, no matter the brand, because they all try to look & function similarly. When i use them on my bottom teeth, i have to readjust my hand position. When i do that, my finger comes off of the power button. So, when i want to turn it off, I can't always find the correct button immediately. If I take it out of my mouth to look, water squirts everywhere. The only other option is to let all the water run out. Very frustrating, but i had the same issue with every one of these water flossers. I just need to get used to this one.I saw some mention the water runs out too quickly. It's fine for me. I get between every tooth, & there's still water left. It has good power, & has worked great so far. Of course, i can't speak to longevity yet, but with a 2 year warranty, i hope it will be fine. My last 2 were gifts, so i had no receipt to get sonicare to fix them. I also haven't seen how long the battery lasts, but that's not a huge deal for me, as i have an outlet in my bathroom to charge easily. This device does everything i expected, & works great. I like the sonicare tios better, because they have a bit of rubber on them that i can sometimes touch my gums with to make sure I'm getting between my back teeth. The tios on this are just hard plastic, so i will need to learn to use them differently, or just keep using the sonicare tips for now.Edit 2 on 2/18/25: i updated the review a few minutes ago to say there was no charging light, but then i looked at the manual which says there is. So, i tried a different cable, & it does actually have charging lights (the same lights that tell which mode you're using). The cable i used was a USB-C on both ends, & is fast charging for my phone. I tried the USB-C with a USB-A end like the device comes with, & it actually does have a charge light, & i was mistaken. Sorry for not checking this before updating the review.The device is still working great, but i wasn't sure it had a "battery low" light, so i wanted to charge it (I've had my sonicare flosser run out of battery mid use, because i wasn't paying attention to the "battery low" light). It's been 1 month & it's still on the very first charge. I had to charge my sonicare at least once every 2 weeks, sometimes more frequently. The battery is amazing on this device.They also sent me some free replacement tips for registering the device for the warranty, so that's cool, & something potential customers should know, too.

Nice unit at great price. Tried it out today and yes I like it much better than flossing. So it makes me want to floss using this new water pick. It really does do a great job. Takes a little getting use to but it gets easy after 2 or 3 times. I say buy one at this price and good quality you can't go wrong.

Plenty of options for water pressure and pulsing. This flosser works so well that I stopped flossing with string floss. I tried flossing with string floss after my first week's usage of the water flosser and NOTHING came out from between my teeth or on the floss so I know it works better than flossing for me.The battery charge lasts a very long time. After 2 weeks of flossing, I plugged in my charger and it was at 75% (4 of 4 lights). I now just top off the charging after a month.

I got this for my kid who got a palate expander and braces and he’s been using this to clean his mouth. It’s a little bit of a learning curve for a little boy to maneuver (it’s pretty large in his hands) but once he got the hang of the water stream and strength, it’s been great. It’s very effective as a cleaning room and works very well. One charge goes for weeks and weeks so it’s very low maintenance. I ran into an issue when I had to charge it 2 months later, but the fault is entirely mine. If you’re like me, you opened up the water floss, popped the one attachment you use into the unit, shoved all the other attachments into a drawer and threw the usb charging cable into your cable drawer and forgot all about it. This unit will not charge if you use a charging adapter with a USB-C to C cable. You need to use a USB-A to USB-C cable and attach it to a charging adapter that plugs into the USB-A end (A is the old USB type with the rectangular tip that only plugs into things one way). If both ends of your cables are USB-C, it won’t charge.

Son just got braces and he loves it. Works great, no issues and easy to swap out different nozzles.

Who should buy / who should skip: Good pick for budget shoppers or travelers who want fewer refills and simple controls. Skip it if you need strong, consistent pressure for heavy plaque.I bought the COSLUS C30 to see if a budget cordless flosser could replace my older unit. I’ve used it twice a day for three weeks, mostly at the sink after brushing.The wins are straightforward. The 300 ml tank is the star; one fill gives about 90 seconds, so I don’t have to pause mid-clean. The pressure presets and memory fit my routine-I keep it softer in the morning and stronger at night-and a full charge lasted a little over two weeks. The wide-mouth reservoir rinses and air-dries quickly, which helps it stay fresh between uses.Trade-offs show up in the build and performance. The plastic body feels light, and the charging flap doesn’t always seal, so I towel it off after rinsing. Tip changes can feel sticky when the release button catches. Most important, the pressure is fine for maintenance but less punchy and less consistent than my Waterpik cordless, especially around tight contacts. On the other hand, the COSLUS costs less and the larger tank means fewer refills, which is great for travel or a simple nightly routine.A pleasant surprise was how fast the tank dries after cleaning-less leftover moisture means fewer stale smells during the week. A small annoyance not obvious from the listing is that you get a USB cable but no adapter, so plan to use your own.Verdict: 3 out of 5. Strong tank and decent battery at a friendly price, limited by a light build and average pressure. Best for first-time flossers or travelers; power seekers should look higher up the range.
