Why do we have to need strong waterproof ability? Because you use the electric brush in the humid environment. If the brush cannot resist water well, it is easy to get malfunction because of water invasion usually after about 6~12 months. What is high frequency good for? High frequency (Strokes Per Minute) break the water and toothpaste into very small particles for cleaning hard-to-reach areas of teeth. Higher frequency means strong cleaning ability that's better for oral health. Do I really need so many brushing modes? It doesn't hurt to have more options for brushing and whitening teeth. If you need to focus on your favorite mode, our brush can remember the mode that you use last time and activate automatically when you switch on the brush. Why do we need such a long duration electric toothbrush? You need to believe good products don't waste your time in charging them. When you go for a business trip or journey, you'll never worry about forgetting the USB cable or charger because you don't need them at all now.
