Satisfied, so far.
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.

Been using this since 2024—still works great
I’ve been using this water flosser since 2024 and it’s still working really well. It’s easy to use and feels like a good addition to my daily routine. I like that it has different modes so you can adjust the pressure depending on what feels comfortable. The water tank is a good size and doesn’t need to be refilled too often. It’s also convenient for home or travel, and I’ve had no issues with it so far. Overall, I would recommend it if you’re looking for an easy and effective way to keep your teeth clean.

Great power and water capacity
This works great and I love the DIY setting. Also comes with an extra nozel so my husband and I don’t have to share one. The battery lasts long and it holds enough water to thoroughly clean my teeth before refilling.

COSLUS WATER FLOSSER (Love it!!)
Already love it and can tell it gets the job done great with just the first use. I love this floaser already even though it is a little rough. I say this because have had an other water flosser before that was softer than this one with the water shooting out and still did a great job, but besides that this water flosser is great and affordable, quiet, charging great and is portable!

Great product and price.
Easy to use right from the box and I can travel with it. It's a great product and price. I sent one to my sister and she likes it too.

You don't know which one you'll get
I bought one of these back in January, green color, and love it. So last week I hit the "buy again" button, because I wanted a second one to keep in a different location where I stay frequently. What arrived is significantly different than the first one I bought, and I don't like it nearly as much. The biggest difference is the charging port. On #1 it's a standard USB-C input. On #2 it's some connector I don't recognize, if I lose the cord that came with it, I'm out of business. On #1 the buttons are the membrane type, nowhere for water to penetrate except maybe the top edge of power button. On #2, the buttons are raised and have a crevice all the way around them. Last, #2 doesn't have as powerful a spray as #2. Note that they came in completely different boxes, I suspect #2 is old stock and #1 was a newer update. I'd give #1 five stars, but #2 only two, so three stars overall. If you buy, hope you get the one with the USB-C port.
