Value

With an MSRP of $229.99, the DiamondClean Smart 9300 sits at the top end of electric toothbrushes in terms of price. It does deliver excellent cleaning performance and a high-end user experience.

For those seeking the ultimate brushing experience with real-time guidance, it’s a great choice despite the premium price.
