Oral-B Pro 100 Battery Toothbrush vs AquaSonic Black Series Toothbrush

The Black Series is the stronger buy for most people. It runs a 40,000 VPM sonic motor with four modes, an ADA seal, a rechargeable lithium-ion battery rated for four weeks, IPX7 waterproofing, eight DuPont heads and a hard travel case. The Oral-B Pro 100 is a basic battery-powered oscillating brush that takes two AA batteries and includes one extra head. It is simpler and lighter, but it has fewer features, no rechargeable battery and no written warranty. Owners of the Black Series praise the clean and the included heads, but some report the mode button switching mid-brush and weak customer service.

• Choose the Oral-B Pro 100 if you want a low-cost, no-charging brush that runs on AA batteries for travel or a backup, and you trust the Oral-B name for oscillating cleaning.
• Choose the Black Series if you want a rechargeable sonic brush with multiple modes, a long battery life, a travel case and a two-year supply of brush heads in the box.
