Review on 🦷 Ultrasonic Electric Toothbrush: U-Shaped Automatic, 360° Whole Mouth Whitening, Wireless Charging, IPX7 Waterproof - For Adults by Krista Johnson

I've been hoping for this item for years. It's pretty easy to summarize the experience with this item: The bristles don't vibrate, so the brush is ineffective unless you manually move the mouthpiece in your mouth and remove it. To be precise, the bristles vibrate a bit, but that's because the charger's base carries vibrations, so the bristles are only shaken by the vibration of the base. The product is not made with love or perfection, it is a prototype idea developed with no intention of ensuring efficiency and quality
