New Aquasonic Black Series Ultra Whitening Toothbrush

This multi-function electric toothbrush has 4.6 of 5 stars from 107K reviews on Amazon, but unfortunately the high pitched noise it makes triggers my dentist phobia. AquaSonic Black Series Smart Toothbrush,  40,000 vibrations per minute, a lithium-ion battery, ultra-fast wireless charging, 4 mode operation, smart vibration timers, 8 DuPont engineered brush heads, and a custom travel case. Each brush head lasts 3-4 months so 8 will last for about 2.5 years. Black Series can last 4 full weeks (2 min/2x a day) on a full charge so it's perfect for on the go travel with the included travel case. I have opened the packaging and charged the unit, but it is otherwise new and unused.
