Packaging and delivery set

The Dr. Bei BY-V12 sonic toothbrush comes in a relatively small black box made of thick cardboard, so that the device can easily survive transportation by mail. The box is very informative, contains an image of the device and basic information, characteristics of the toothbrush.

Inside the box, in a black plastic tray, there is a transport case with a transparent plastic lid, inside which there is a toothbrush carcass and two replaceable attachments.

Under the case is a cardboard partition separating two compartments, one of which contains a charger, and the other, an additional replaceable attachment and operating instructions in English and English.


The plastic case of the device, 25 mm in diameter, has a five-layer black coating, is made in a classic cylindrical shape and, of course, is made in accordance with the IPX7 standard.

On one of the surfaces there is a single, multifunctional device control button, which has a textured surface that somewhat resembles a fingerprint, thanks to this surface, the button is perfectly felt even in the dark. Slightly below the control button there are three indicators of the device’s operating mode and one indicator showing the state of the battery (lights up red if the battery charge level is critically low).

Switching between operating modes is carried out by pressing the control button again, within 15 seconds after turning on the device.

On the bottom surface of the toothbrush there is a special recess, which is installed on the corresponding protrusion located on the charger.

On the upper surface there is a flat-faced shaft on which the toothbrush head is mounted.

The manufacturer himself claims that the case is resistant to stains and streaks from water.

During the operation of the toothbrush, you can notice the minimum vibration of the body, which is achieved thanks to the use of a modern brushless motor, it is the motor that ensures the quiet operation of the device.

The charging station is equipped with a non-removable USB cable on one side and a flat pad with a small projection on which the toothbrush fits on the other side.

In addition to the toothbrush, the package includes three attachments.

  • The CLEAN brush head is made with DuPont bristles, which are great for whitening teeth and can remove coffee and tea stains on your teeth.
  • GYM tips are designed for sensitive teeth. The manufacturer says that white bristles are great for everyday dental care, gray bristles are for cleaning gum pockets, and blue bristles with silver ions are essential for cleaning wisdom teeth. All bristles on this brush head are antibacterial.

Of course, we must not forget about the convenient transport case, which consists of two halves, the upper one is transparent plastic, the lower one is black plastic, inside which there are special trays for storing the carcass of a toothbrush and two replaceable attachments.

I would also like to draw your attention to the fact that the Dr. Bei BY-V12 sonic toothbrush is equipped with a magnetic levitation motor with a vibration frequency of 31,000 rpm, a torque of 600 kgf.m, a bristle tilt range of 5.5 mm and a vibration level of less than 55 dB.

Management, operation, autonomy

As mentioned earlier, control of the Dr. Bei BY-V12 toothbrush is carried out with a single button. A single press of the control button activates the operation of the device in the whitening mode, this mode, according to the manufacturer, can significantly increase the whiteness of the enamel of the teeth and get rid of plaque. Pressing the button twice activates the gum care mode that is best suited for people with sensitive teeth. The third press of the button activates the SPA mode, which combines a three-minute alternation of gentle and whitening modes.

Unfortunately, it is difficult to convey the differences in these operating modes in words, the most demonstratively this can be seen in the video, when the head of the toothbrush is applied to the table surface. The difference just feels great.

During operation, the toothbrush informs the user about some events:

  • After 30 seconds, there is a notification about the need to change the cleaning zone to ensure a more thorough cleaning of the teeth;
  • After 120 seconds, there is a reminder that the cleaning process is over.

The battery life deserves special respect, and here it is quite decent. The manufacturer promises that from one charge the Dr. Bei BY-V12 toothbrush will work up to twenty days, and we are talking about using the toothbrush twice a day for two minutes, each time. This is actually a pretty decent battery life. The device fits perfectly into the included transport case, which, in turn, easily fits into any bag. The Dr. Bei BY-V12 toothbrush will be simply irreplaceable on a business trip or on a trip.

A complete induction charger is used to recharge the battery. A full charge takes about four hours.
