Simply the Best
Philips Sonicare DiamondClean Smart 9500 Series
"The first Sonicare made the list 20 years ago, and it's only gotten better—literally one of my favorite things that I use twice a day. This year's version is a smart toothbrush with an app that gives feedback on brushing habits, four supereffective brush heads for different cleaning modes, and sensors to adjust intensity or tell you if you missed a spot. Trust me, you'll look for excuses to brush."—Oprah
