The Amazon Prime Day Sale is over, but there are still some great opportunities to snap up a brand new electric toothbrush for a fraction of the often sky-high price. But which model is truly worth your hard-earned money? We may have an easy answer to this question.
The price of our all-time favorite Oral-B Genius X Limited has been slashed in half, bringing it down to just $99.99 — a round saving of $100.
The Oral-B Genius X takes the well-deserved top spot in our guide to the best electric toothbrushes on the market, having previously scored an impressive 4.5/5 rating in our review. This premium toothbrush blows its competitors out of the water with its excellent brushing performance, compact design and a sheer array of smart features. Unlike most models in this price bracket, the Oral-B Genius X is powered by artificial intelligence to help you step up your brushing technique and therefore get the best possible results out of your daily chores.
The interactive app will meticulously track your movement patterns and brushing habits, giving you simple and actionable prompts — it is like having a pocket-sized dental hygienist. What is the caveat then, you may ask? The Oral-B Genius X can be quite noisy. But for just $99.99, it really is just a minor inconvenience.
