Review on Electric toothbrush Oral-B Smart 4 4900, black/pink by Jeong Hoon (Kim) ᠌

If you have never used electric brushes before, you may want to select a set that is more comfortable for you, but in general, I am quite pleased with the acquisition because it does an excellent job of cleaning. I went with this particular set rather than the most basic one because it has three different modes for cleaning, which I find very convenient. I didn't understand why charge indicators were necessary; at first, I believed that they would display the amount of charge that was left, but in reality: one indicator flashes when charging (green), and the second one starts flashing red 30 seconds before the brush is completely discharged (while the speed is noticeably dropped, and you can guess about the discharge even without this blinking), one indicator flashes when charging (green), and one indicator flashes when charging (red). This is a clear disadvantage, as it prevents you from cleaning one half of your teeth. The Bluetooth technology is just there; out of sheer curiosity, we linked one brush to it, but we didn't uncover anything really fascinating.
