The Rolls Royce of Toothbrushes
Let me start by saying this: if my teeth could throw a party, theyâd invite the Philips Sonicare DiamondClean Smart 9500 as the guest of honor. This toothbrush is the Beyoncé of oral careâexpensive, yes, but absolutely worth it. Sure, my wallet cried a little, but my teeth have never been happier, so I consider it a fair trade.Durability: This thing is built like a tank. Iâve dropped it more times than Iâd like to admit (blame my morning clumsiness), and it still works like a champ. Itâs survived my butterfingers and my dogâs attempts to steal it for a chew toy. If this toothbrush were a person, itâd be that friend who always has their life together while the rest of us are just trying to survive.Charging Capability: The charging glass is chefâs kiss. Not only does it look like something Tony Stark would design, but it also charges wirelessly. No fumbling with cordsâjust plop it on the glass, and it powers up like magic. The battery life is impressive too. I charged it once, forgot about it for weeks, and it was still going strong. Itâs like the toothbrush version of a marathon runner.Travel Case: The travel case is a game-changer. Itâs sleek, compact, and even has a USB port to charge the brush on the go. I took it on a weekend trip, and my friends were so impressed they thought I was secretly a millionaire. Jokeâs on themâI just have impeccable taste in toothbrushes.Value for Money: Yes, itâs pricey. Yes, I had to convince myself I deserved it. But after using it, I can confidently say itâs worth every penny. My dentist even complimented my teeth at my last checkup, and that alone is priceless. Plus, if you divide the cost by the number of times youâll use it (twice a day, every day), itâs basically a bargain. Math!

Worth the price !!!
This product is a toothcare machine !!! It’s worth the price compared to a cleaning at the dentist’s office since it’s like a professional cleaning each time you use it !!! Also, my bathroom counter has never looked better.

Leaves teeth as clean as when you get a cleaning at the dentist.
Excellent gum care, and my teeth feel as squeaky clean as after a cleaning at the dentist.The settings are very easy to use, and adjust.Very functional yet sleek design, and easy to charge whether you are home, ( with the glass, or just the small attachment to the base.) or on vacation in the case.The size is bigger than a typical manual toothbrush of course, but really not too big, it fits easily in my hand.Overall the value is great because it keeps my teeth clean from plague, and helps to prevent cavities from forming.

Waste of money
I purchased the Philips Sonicare DiamondClean Smart 9500 less than 6 months ago, and it has completely failed. The toothbrush head no longer fits securely, making it far less effective, even though I only use official Sonicare replacement heads. On top of that, the body makes an incredibly loud, unpleasant rattling noise. I’d rather use it as a manual brush to avoid the annoying sound it now makes. For such an expensive product, this level of quality is unacceptable.

Nice toothbrush, but you can probably get away with a less expensive one.
Sonicare is a great line of brushes. I thought I would like and use the app, but it’s tracking is not super accurate. If I had known, I would have gone with a cheaper version. The brush itself does a great job. I was amazed at the difference when i switched to an electric toothbrush and this one does better for me than Oralb.

So happy with this purchase!
I had an older sonicare toothbrush that stopped working after several years, so after reading reviews, I ordered this. I love it! Unlike my other sonicare, I can really feel this one working and doing a great job to clean my teeth. I have not used the app yet.

I purchased the Philips Sonicare DiamondClean Smart 9500 on September 11 for $273.61 SGD ($203.48 USD), and it has completely failed after just two months of use. The toothbrush head holder is loose and doesnât hold the brush properly, while the body makes a loud, awful rattling noise. This is unacceptable for such an expensive product.

Very poor quality control. It is unable to charge on arrival. Terrible!
