I'd be lost without it.

I've had Sonicare products/toothbrushes since they came out. There is no other clean, along with the feeling. Diamond clean most certainly removes plaque/tartar and keeps it away. Your brighter smile will reflect that. The new charging travel case is a bonus.

Pros

Effectiveness, design, ease of charging. Multiple replacement brushes to fit your needs.

Cons

Can't always find Coordinating brush heads that match body. e.g. Black body to white brush head

This product gets the job done

The DiamondClean 9000 has many features. Love how it times each section in 20 second intervals so you don't over or under brush. The app is great for knowing if you are applying too much pressure. Also tells you when to replace your brush head.

Pros

20 second timer per section, advises when to replace your brush head
