I have been using Oral-B or Philips Sonicare ultrasonic toothbrushes for many years, at my dentist’s recommendation. In August, I replaced my old, expensive ultrasonic toothbrush with an excellent and surprisingly inexpensive model (from a lesser-known brand), which has smaller brush heads that fit into hard-to-reach areas, soft, rounded bristles that are gentle on my aging gums, and a choice of five brushing modes.
Even though my new sonic electric toothbrush had great customer reviews and was highly recommended by a well-known and respected YouTube influencer whose product recommendations I have come to trust, I was still a bit skeptical about the quality of such an inexpensive product. However, my oral health team was impressed with the state of my teeth and gums during my routine dental cleaning and checkup 10 days ago. I'm delighted that my new brush has been dental hygienist- and dentist-approved.
I'm excited to share my product review of this terrific electric toothbrush set, which comes with seven regular brush heads, an interdental brush head, and a fitted case for storage and travel and costs just $19.99 on Amazon as of October 12, 2023.
Note: The brand I purchased, Dnsly, is no longer available, but the TEETHEORY and Fairywill brands make nearly identical models with the same features.
Why This Sonic Electric Toothbrush Is a "Best Buy" For Savvy Consumers
Here are some of the key features that make this Sonic Electric Toothbrush Set With 8 Brush Heads and Travel Case a smart purchase.
40,000 VPM for Effective Cleaning and Plaque Removal
Although the American Dental Association says that both manual and electric toothbrushes can clean teeth effectively when using the correct brushing technique, clinical studies have shown that “electric toothbrushes, which combine ultrasonic and sonic (or acoustic and mechanic) actions, may have the most promising effect on good oral health” compared to manual toothbrushes.1
It vibrates at up to 40,000 VPM (vibrations per minute), which is in the same ballpark as many ultrasonic toothbrush models from Philips Sonicare and Oral-B.

Choice of Five Brushing Modes
There are five tiny LED lights down the front of the handle labeled W, C, S, P, and M, respectively, that allow you to choose among the following brushing modes to customize your oral health care routine:
- White mode (W): strong vibration helps whiten and brighten teeth by removing surface stains.
- Clean mode (C): medium vibration for routine cleaning / twice-daily brushing.
- Sensitive mode (S): gentle vibration for first-time electric toothbrush users or those with sensitive teeth and gums.
- Polish mode (P): strong vibration/invert frequency helps polish and brighten teeth.
- Massage mode (M): gentle vibration/invert frequency for gum massage and increased circulation to improve the health of your gums.
- Note: I could not find any information on what "invert frequency" means (or does) in the context of electric toothbrushes.
Just press the large Power on/off button (inside the gold circle) repeatedly to cycle through the different modes. The nice thing is that it will remember the mode you used last and return to that setting automatically the next time you press the Power button.
I have used the Clean, White, and Massage modes so far. I think the White mode is gentle enough for daily use, thanks to the soft, rounded bristles on the brush heads.
2-Minute Smart Timer With 30-Second Quadrant Reminders and Auto Shutoff
Most dentists recommend brushing your teeth for 2–3 minutes, or 30–45 seconds per quadrant. This sonic electric toothbrush pauses after each 30-second interval to let you know it's time to move on to the next quadrant, then shuts off automatically after two minutes.
7 Brush Heads and 1 Interdental Brush
The American Dental Association recommends that you replace toothbrushes, or brush heads for an electric toothbrush, every three to four months (or sooner, if the bristles are visibly frayed).
The brush heads have blue bristles at the top and bottom that, with use, gradually fade from blue to white as a helpful reminder to discard and replace the brush head.
I really like the smaller brush heads and the thin, pointed, interdental brush head with white bristles, since both make it easier to get into tight, hard-to-reach areas. The interdental brush is also great for cleaning around and in between dental braces.
The DuPont bristles with rounded tips are gentle on gums and enamel, which is another reason I decided to try this set.
30-Day Rechargeable Battery Life
A full charge, which takes 4 hours, lasts for about 30 days, based on brushing for two minutes twice a day.
USB Charging (Charging Cable Included)
The included USB cable can be plugged into any socket with a USB interface, such as a car, laptop, or phone charger adapter or power bank socket. You can keep both the cable and an inexpensive USB wall charger/plug adapter in the bathroom for when the battery needs charging (roughly once a month).
This sonic toothbrush has a low battery indicator that lets you know when it's time to recharge it. It also automatically shuts off after the battery has been fully charged to prevent overcharging.
Fitted Travel Case and Protective Brush Head Cover
The hard plastic, fitted toothbrush travel case has molded sections to hold the handle, one brush head, and the interdental brush head. There is also a space-saving clear, hard plastic brush head cover if you want to travel with just the handle and one brush head, rather than the larger, fitted storage case that also holds the interdental brush head.
IPX8 Waterproof
The IPX8 Waterproof rating (an improvement from the IPX7 Waterproof rating on my Dnsly brush) means your electric toothbrush can survive immersion in fresh water up to 1.5 meters deep for 30 minutes without damage.
You can thoroughly clean the entire brush with soap under hot running water and even brush your teeth while you are taking a shower if you wish!
Lightweight
The brush itself weighs just 55g, "less than half of ordinary sonic toothbrushes" according to the manufacturer's product information.
Two Color Choices
I purchased this set in black, but it also comes in pink.

Less Than $20 for the Entire Set
At just $19.99 for the black or pink set, with free shipping for Amazon Prime members as of 10/12/23, this set delivers a huge bang for the buck.

| Available on Amazon |
You can also get a set of two sonic toothbrushes, one black and one pink, with 12 color-coordinated brush heads (five of each color), 2 color-coordinated interdental brushes, and 2 color-coordinated fitted travel cases) on Amazon for just $39.98. Having two sets in different colors makes it easy for spouses, partners, siblings, roommates, etc. who use them to tell which toothbrush is theirs.
Features Not Included in This Sonic Electric Toothbrush Set
Even though this set is excellent and a tremendous value, there are a few features that some of my previous Oral-B and Philips Sonicare ultrasonic toothbrushes had that this one does not.
No Charging Base
The only way to charge this sonic brush is with a USB cable (included). While many people prefer this method, some may prefer having a dedicated charging base plugged in near the bathroom sink.
Since hearing several respected medical and dental experts advise "Don't brush where you flush," I have started storing my toothbrush in my bedroom instead of my bathroom anyway, so the USB charging requirement isn't an issue for me.
No Battery Charge Level Indicator
My last Oral-B ultrasonic toothbrush had four stacked LED lights on the handle to indicate how much charge was left. I used to store the toothbrush on its charging base, however, so I never looked at it unless I was traveling for an extended period.
The low battery indicator works fine for my purposes.
No 3-Minute Timer Option
I liked the choice of 2-minute (30-second intervals) or 3-minute (45-second intervals) brushing times on my pricy Oral-B model. However, if I want to spend a bit more time on certain areas, it's easy enough to press the mode button of my choice to resume brushing after the 2-minute automatic shutoff.
Note: None of my Oral-B or Philips Sonicare toothbrushes had Bluetooth connectivity or wireless fast charging, and neither does my new brush. However, one or both of these features are built into many of the newer models from these leading brands.
The Perfect Travel Toothbrush
Even if you don't want to replace your current ultrasonic toothbrush, this very inexpensive sonic set would be great to keep in your carry-on luggage for traveling, thanks to its long battery life, convenient USB charging, toothbrush travel case, and protective brush head cover.
A Great, Affordable Gift Under $20
This electric toothbrush set would make a great gift for anyone who is currently using a manual toothbrush, wears braces, is a college student, or has difficulty getting their current toothbrush into hard-to-reach places.
It also makes a great stocking stuffer. No one would guess that this set, complete with a travel case, brush head cover, seven brush heads with fading bristle replacement indicators, an interdental brush head, and a USB charging cable, costs less than $20!
