The Philips Sonicare DiamondClean 9000 electric toothbrush duo has seen a price drop to $489 at Amazon Australia, down from the usual $619, ahead of Prime Day which officially begins next Tuesday, July 7. Over 100 Aussies have already purchased the duo since the discount went live.
Smart Features for Oral Health
Described as a “game-changer for oral health,” the toothbrush offers multiple intensity levels, a built-in pressure sensor that lights up when brushing too hard, and in-app tracking. Users report their teeth “feel clean and fresh” after use.
“I got this toothbrush as a gift for a family member, and honestly, it’s been a game changer for their oral health,” wrote one shopper. “They’ve got sensitive gums, so finding something that cleans well without feeling too harsh has made a huge difference.”
Why Shoppers Recommend It
The pressure sensor is highlighted as particularly useful for protecting gums. “It lights up when you’re pressing too hard, which is a great little feature. It’s also super convenient for travel since it’s portable and holds a charge for a long time,” added the shopper.
Another reviewer noted: “The built-in pressure sensor is a great feature to protect gums, and the brushing performance feels noticeably better than a manual brush. Stylish design with a convenient glass charger makes it feel premium. A bit pricey, but worth it for the quality and results.”
Expected to Sell Out Fast
With the duo now under $500, it is expected to fly off virtual shelves. Shoppers agree the model is a considerable upgrade from a manual toothbrush, delivering a “powerful yet gentle clean with multiple modes and intensity settings to suit different needs.”
The deal is available now on Amazon Australia, ahead of the official Prime Day event.
