A very good electric toothbrush attached to a replacement-head business. The long-term satisfaction question is almost entirely about what the heads cost and whether the unit survives past warranty.
This entry is written from the 4 sources listed at the bottom of the page. The numbers are our editorial estimates drawn from that material, not measurements, and no statistical sample sits behind them.
It depends on how you will use it. 72% would buy it again, which means roughly 28% would not. Head cost is the ongoing expense people underestimate.
Your teeth are cleaner and you have now bought heads twice. That subscription-by-stealth is what the score reflects.
Head cost is the ongoing expense people underestimate. Charging and motor failures appear across owner review sites. Out-of-warranty repair is not an option.
Worth it for: People who will use the pressure sensor properly; Upgrading from a manual brush; Households sharing one handle with separate heads. Think twice if: You resent proprietary consumables; A cheaper sonic brush would do; You want something repairable.
