Bitvae R2 review


The Bitvae Smart S2 Electric Toothbrush features a sleek and ergonomic design, making it comfortable to hold and angle during brushing. The handle has user-friendly controls — one button to turn on and change modes — allowing for easy mode and intensity adjustments. The modern aesthetic adds a touch of elegance to any bathroom.

Head technology

The S2 features an industry-leading ultrasonic motor that generates an impressive 40,000 micro brush movements per minute. This advanced technology ensures more effective plaque removal than manual toothbrushes, resulting in healthier gums and whiter teeth. The high-frequency vibrations penetrate hard-to-reach areas, providing a thorough cleaning experience.

Cleaning modes

The Bitvae Smart S2 offers five brushing modes: Clean, White, Soft, Gum Care, and Smart, letting you personalize your brushing experience depending on your oral care needs.

Smart features

When brushing with excessive force, the sensor alerts users, helping to prevent damage to the gums and enamel. This feature promotes a gentle and effective brushing technique, ensuring optimal oral health.

One of the standout features of the Bitvae Smart S2 is its exceptional battery life. With a fully charged battery in just 4 hours, the toothbrush can be used for up to 100 days, vastly surpassing the battery life of many other toothbrushes. This extended battery life frees you from frequent charging concerns, making it ideal for home or travel use.

Timer and replacement brush heads

The built-in 2-minute timer of the Smart S2 Electric Toothbrush ensures that you brush for the recommended time, with a reminder every 30 seconds to change brushing areas.

Our final take

What we like:

  • The toothbrush comes with eight replacement brush heads, so it will be 2 years before you need to purchase more.
  • The inclusion of a travel caseand a gadget for wall hanging is a thoughtful addition. It enhances portability and convenience, so you can maintain your oral care routine even when traveling.
  • The toothbrush is a budget-friendly option, making it accessible to a variety of income levels, and it offers plenty of features for the cost.

What we don't like:

  • The power of the toothbrush is not on par with better-known brands. While it still offers effective cleaning, those accustomed to more powerful toothbrushes may find the performance lacking.
  • The charger's design, requiring connection via a pin, is not very comfortable. This aspect could be improved to provide a more user-friendly charging experience.

Overall, the Bitvae toothbrush offers a great budget option for those looking for the greater plaque removal that electric brushes provide. We love the multiple replacement heads and a travel case with a wall-hanging gadget. However, there are areas for improvement, such as enhancing the toothbrush's power and providing a more convenient charging method.

Considering its affordability and the features it offers, the Bitvae toothbrush presents a compelling choice for those seeking a cost-effective oral care solution.
