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
