Summary
The best value entry into Oral-B's premium iO line. The magnetic motor feels noticeably more powerful than older Oral-B models, and the user-replaceable lithium-ion battery is a long-term durability win.
Tom's Guide calls it the best kids' electric toothbrush, with an ergonomic grip, 2-minute timer, pressure sensor, and gentle oscillating movement sized for small mouths. Wirecutter also notes the Pro 1000 handle works with Oral-B's kid-size heads as a family-friendly alternative.
