Someone remains true to the classic toothbrush, but many prefer her an electric model that takes care of the cleanliness of teeth much better. However, it can be replaced by new automatic models called Be, which work without batteries and not mains.
The principle of operation of the novelty is the same as that of electrical analogs: at a speed of 40,000 rpm, it takes 120 seconds,to perform hygiene procedures. At the end of cleaning, it beeps. The advantage is that the model does not require the purchase, replacement and recharging of the battery. It works from the kinetic energy of the two springs. To start the mechanism, the user only needs to scroll a little twice a small wheel located at the bottom, and press the power button. So no more charging stations, no wires to keep at hand.
In the kit there are three replaceable nozzles for the oral cavity, they are enough for a year of use, and an ergonomic cover-case, convenient for travel. All components are made of biodegradable materials.
