$80 might seem like a lot to invest in a toothbrush, but the Oral-B Pro 7000 includes six brushing modes, a Bluetooth connection that gives you real-time brushing feedback and advice on your phone, and even an LED light built into the handle that glows in different colors to tell you when it’s time to switch quadrants, or when you’re brushing too hard.

$80 is as cheap as we’ve ever seen this model, just note that this exclusive to Prime members.
