Shengbei JS309 Smart Sonic Electric Toothbrush: 32,000 RPM frequency
For anyone tired of guessing if they brushed long enough or too hard, this smart electric toothbrush brings precision to your daily routine. It's not just about cleaning teeth; it's about building consistent habits that protect your gums and enamel over time.
The built-in timer ensures you brush for the full two minutes dentists recommend, while the pressure sensor gently alerts you if you're scrubbing too aggressively. You'll feel a subtle pause in the vibrations, a reminder that saves your gums from wear. With multiple modes like sensitive and whitening, you can tailor each session to your needs, and the Bluetooth app tracks your progress to keep you motivated. This toothbrush is waterproof and offers a 30-day battery life, making it reliable for home use or travel. It includes four soft brush heads and charges quickly via USB, so you're always ready to go.
