What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the DiamondClean Smart 9500 is the most app-integrated brush in this roundup, with 15 brushing settings, BrushSync replacement reminders, and position-aware coaching via the companion app. electricteeth.com (high trust) calls it 'one of the best brushes on the market today,' praising the box contents and clean quality while noting it has 'more features than you need.' techgearlab.com (high trust) corroborates this with their own cleaning-test results, calling out comfortable feel, solid battery life, and 'doing very well in our cleaning tests.' The community picture is messier. r/BuyItForLife and r/Costco threads include long-time Sonicare loyalists who prefer the DiamondClean head feel to anything else, but also posters arguing the premium 9500 is overpriced versus the 9300 or even the mid-range 5300/6500 — and that 'without true smart coaching, even at $90/handle this feels overpriced.' The 4.3-star Amazon average across roughly 1,400 verified buyers is the lowest of our top five, which tracks with that 'too expensive for what it adds' theme.
What reviewers liked
- electricteeth.com (high trust) rates it among the best brushes on the market
- techgearlab.com (high trust) confirms strong cleaning-test results and solid battery life
- Best-in-roundup app integration with position tracking, 15 settings, and BrushSync reminders
- Premium glass charger and travel case included
Where it falls short
- 4.3 Amazon average is the weakest of our top five
- r/Costco and r/BuyItForLife threads question whether the app coaching justifies the premium over the 9300 or 6500
- electricteeth.com itself notes it has 'more features than you need'
- App is the headline feature but several community threads describe the experience as a 'little rushing' and not consistently useful day-to-day

For a buyer who specifically wants app-driven brushing analytics — position tracking, problem-area maps, brushing history — this is the strongest pick in the category. For everyone else, even the high-trust reviewers we read steer downmarket.
