Some drawbacks but overall Good- BUY SEPARATE CHARGING CORD
Color: Black
I have had this for about a week now and here are my takes so far:
You have to order the charging cord separately which is weird, but I was able to get out delivered quickly with Amazon Prime so just know to do this when you order.
Pros: The price!
The water tank is surprisingly large compared to WaterPik and you can definitely use it for longer to clean because of this.
There are lots of different options for water strength and different tips that come with the device
In the first week it has worked fine.
Cons: It is a little too easy to accidentally hit a button and change the water pulse when you are holding it- I have to be very conscious of where my hand is so I don’t get the super strong flow (it is very strong)
The little door where you add water to the tank is at the bottom and seems like out would be easy to knock it off accidentally when open. I did do this once but nothing broke so I was able to snap it back on easily.
I dropped the device about six inches into my sink (all of these devices can be slippery) and the tank got nudged off, but I was able to easily re-attach it so no real problems there.
There is a little detached plug you use to cover the charging connection and it seems like it would be so easy to lose the little thing. 🤞🏼
OVERALL: I would buy again as overall it works well, and the last WaterPik I bought died after 2 weeks (so I don’t trust those anymore). Just be mindful of how you hold it, and watch out for the little tank door and the little rubber charging cover!

2+ Years of Use and Still Going Strong!
Color: Black
I’ve had this Nicwell Cordless Water Flosser since July 2023, and it has been incredibly reliable. After nearly two years of daily use, I’ve never had any battery issues or pressure problems, which is usually the first thing to go on these portable units.
Why it’s been a great buy:
Dependable Power: The 1400-1800 pulses per minute feel just as strong today as they did on day one. It’s perfect for getting deep between teeth and along the gumline.
Long Battery Life: Even after two years, the rechargeable lithium battery holds a charge for a long time. I don't find myself constantly reaching for the charging cable.
Truly Portable: It’s lightweight and easy to pack for trips, yet it performs like a full-sized countertop model.
4 Versatile Modes: The "Clean" and "Custom" modes are my favorites for a thorough deep clean.
If you want a water flosser that actually lasts more than a few months, this is the one. It’s durable, consistent, and well worth the investment!

Replaced after emailing Nicwell customer service….Thank you Nicwell
Color: White
For the first month, the water flosser was everything I had hoped for. It transformed my nightly routine into a refreshing experience, and I felt a sense of accomplishment knowing I was taking great care of my teeth. Friends and family noticed my radiant smile, and I couldn’t help but brag about her new gadget.
However, just as I was settling into my routine, disaster struck. One evening, as I prepared to floss, the water flosser sputtered and then went silent. Confused, I checked the power source and the water reservoir, but nothing seemed to work. Panic set in as I realized that my beloved device had only lasted four months.
Determined to resolve the issue, I dug out the warranty card and dialed the customer service number. After navigating through a series of automated prompts, she finally reached a representative.
“Thank you for calling. How can I assist you today?” the representative asked cheerfully.
“I’m having trouble with my water flosser. It stopped working after just four months,” I explained, his voice tinged with frustration.
“I’m sorry to hear that,” the representative replied. “Can I have your order number, please?”
After a few moments of searching, the representative returned with a frown in their voice. “I see that your purchase was made four months ago. Unfortunately, our return policy only covers the first 30 days. I’m afraid we can’t offer a replacement.”
I felt my heart sink. “But it’s a defective product! I thought warranties covered issues like this.”
“I understand your frustration, but the policy is quite strict,” the representative said, their tone now more formal. “You might consider contacting the manufacturer directly, but I can’t guarantee they’ll be able to help.”
Feeling defeated, I thanked the representative and hung up the phone. I couldn’t believe that a product I had trusted and loved had failed me so quickly, and the customer service I had hoped would assist me had only added to my disappointment.
In the days that followed, I found myself reflecting on her experience. I realized that while the water flosser had been a great tool, the lack of support when it mattered most had left me feeling disheartened. I returned to traditional flossing, albeit with a newfound appreciation for the simplicity of it.
Though the water flosser was gone, I learned a valuable lesson about the importance of understanding return policies and the risks of relying too heavily on technology. And while I might eventually try another model, I would always remember to read the fine print and keep my expectations in check.
However, after reflecting on my situation, I decided to reach out via email to the company. To my surprise, they responded promptly and offered to replace the flosser at no cost. This gesture restored my faith in the brand and showed me that they genuinely care about their customers.
I wanted to take a moment to express my sincere gratitude for replacing my water flosser after just a few short email exchanges. Your prompt and helpful response made a significant difference in my experience, and I truly appreciate your commitment to customer satisfaction.
The water flosser has been a fantastic addition to my dental care routine, and I’m thrilled to have a replacement that I can rely on. Thank you once again for your excellent service and support!

Effective water flosser, good cleaning but depends on expectations
Color: Black
Good water flosser overall. It does a solid job of cleaning between teeth and is convenient for daily oral hygiene compared to traditional flossing.
The different pressure settings are useful, allowing you to adjust intensity depending on comfort level. It’s easy to fill, use, and clean, which makes it practical for regular use.
Battery life is decent, and the device is portable enough for travel or bathroom storage without taking up much space.
Overall, a reliable water flosser that improves cleaning convenience and performs well for everyday dental care.
