An Easy, Effective Water Flosser That Truly Supports Better Oral Health
An Easy, Effective Water Flosser That Truly Supports Better Oral HealthI’ve been in the wellness industry for over 15 years as a certified personal trainer and nutrition coach, and oral health is another component of overall health. If we don't have our teeth, it becomes so difficult to get the valuable nutrition we need in. Plus, bad oral hygiene can come with a bunch of other issues no one wants to deal with.I originally bought this water flosser for my 10‑year‑old daughter after she got braces, since her orthodontist recommended a water pick to help clean between the wires and teeth. And honestly, I wish I had one of these when I had braces as a kid — it makes a huge difference.Flossing is still part of our nightly routine, but this water flosser has become an excellent addition. I was so impressed with how well it worked for her that I bought one for myself, knowing I should have been using a water pick all along. I actually had a traditional plug‑in water flosser sitting under my bathroom sink for years, but I never liked how bulky it was or how awkward it felt to use.It’s rechargeable, portable, and incredibly easy to use. My daughter even takes hers with us when we travel — it’s compact and very easy to pack. The multiple pressure settings make it simple to find the one that feels most comfortable and effective for your gums, and the different attachment heads allow you to customize your cleaning routine. The charge lasts a long time, too, which I really appreciate.I’m genuinely impressed by this water flosser and value it as part of my evening teeth‑hygiene routine. It’s user‑friendly, effective, and a great choice for anyone looking to improve their oral health — whether you have braces or simply want a cleaner, fresher feel.

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.

Highly recommend
Update - This company is outstanding. I contacted them and they responded within 5 minutes. After some back and forth to verify that the product really did malfunction, they sent me a replacement. They always responded within 5 minutes of me sending an email to their support and they stood behind their 24 month warranty. I would buy products from them over and over.Original review - The water flosser died 1 1/2 months after I had it. Only got to charge it once and it is dead. Won't take a charge or respond to any button presses. Junk junk junk.

Great Water Pick
I really like the water flosser, works great. The different settings are great too. I usually refill mine every 2 days, holds a reasonable amount of water, and once charged it’s simple to use. I have had it for about a month and so far so good. I like that the water compartment is removable for easy cleaning. I would buy again.

Love
Got this for my daughter who has braces. She has a plug in water flosser but needed one on the go. For the cost it actually ended up super nice and helpful for her. The purple color is super cute, matches her vibe. Very durable. Very portable. The power is perfect.

Good quality flosser at a reasonable price
I've never used a different water flosser, so I can't compare. But this does everything I would have expected and the price was quite reasonable. The battery lasts incredibly long. The only thing I don't like is that the off/on button is right next the one that changes the mode. Many times, I have inadvertently pushed the wrong button, and the water jet goes berserk while it is in my mouth. It's not a dealbreaker

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.
