AquaSonic Duo Series Pro Sonic Toothbrush vs Philips Sonicare ExpertClean 7700

Buy the AquaSonic Duo Pro if two people share one bathroom and want a complete kit: two handles, ten brush heads, two travel cases and a UV dock. Buy the Philips Sonicare ExpertClean 7700 if you brush alone and want pressure feedback, app tracking and a two-year warranty. The Duo Pro has the stronger motor on paper and the bigger bundle, but owners report cracked plastic and docks that fail around a year. The Sonicare cleans well and has the better smart features, but its battery life is shorter and some units arrive dead or need a long first charge.

• Choose the Duo Pro if you are outfitting a couple or a family and want two brushes, spare heads and travel cases in one set.
• Choose the ExpertClean 7700 if you brush solo and want pressure sensing, app coaching and a two-year warranty.
