Why would you buy a $180 toothbrush when you can get a $20 Oral-B/Braun one? They're not even the cheapest because they are brand, and they're amazing, with no app and a simple design. Don't you realize more expansive toothbrushes are the same, but with stupid apps and tracking sensors? Why would you want that? Edit: Philips seems to be more prevalent than Oral-B in the US but the price ranges are the same. If you want the best tooth brushing experience, a 20 bucks electric toothbrush brush is fine. Any additional dollar goes to gadgety stuff
