We bought this product a roughly a year and a half ago... The cleaning is excellent, it's a pleasure to use and the glass charger is a great design... When it works...
After around 8 months (it's not a clean break) toothbrush start losing power and speed, cleaning less efficiently and making strange noise..
I asked for a replacement (done very quickly by the support team)… Unfortunately, since 3 months, we experiment exactly the same behavior…

it became very noisy and inefficient,it developed brush moment, i disassembled and found a small philips screw and collar in the end that had loosened.Each time i tighten it and even locktite it,it works great for a few days and it is loose again.Is this a known problem?Should I expect more than 10 months operation from such an expensive toothbrush?Can I replace those parts?can I buy just the handpiece by it self?I am reluctant to buy another if same happens again.

The best investment I have done with my money, I just can't wait to clean my teeth everytime I pick up my new electrical toothbrush. It feel like I have just gone to the dentist everytime I finish brushing my teeth.

Perfect clean every time ! it is gentle but extremely effective. I can notice the white of my teeth shining through already- can't live without it. Highly recommended to all my family and friends for the ultimate in teeth care!

My dentist recommended this product.
Having used it, I couldn't imagine using a hand brush or the old electric toothbrush ever again.
The Sonicare should be also recommended for child use who lack the manual dexterity for the old toothbrush.

I have had this toothbrush for a month now and still can't get over how clean my teeth feel. I have had an electronic toothbrush for years (rotating head one) and always considered my teeth to be clean, but this new toothbrush is something else. The vibrating took a little getting used to, but the toothbrush actually works you up to the normal vibration cycle gradually over a couple of weeks. It has multiple different cycles and I will admit that I enjoy the process so much that I tend to do two cycles each time I clean. This is a great toothbrush, highly recommended!

My teeth feel cleaner, it is worth the step up in price, the charger and travel case are great. I am amazed how much better a job it is doing as I had what I thought was a great electric brush already

Pleased I made this fantastic purchase, suffer from bad plaque, cant believe the clean smooth feeling after use.,Love the charging device that lasts for three weeks, slim sleek design, looks good in bathroom.

Bought three of these, one each for everyone in the family. Everyone else's has worked fine but mine stopped working just after two year warranty ran out. It started turning itself on in the middle of the night, even when power was off! Woke me up! And then it just stopped charging. Contacted Philips by email but never got a response. Never used the travel charger so would have loved to have just had to buy a replacement handle rather than a whole new product but cannot see how to do this and Philips didn't respond to my question! Have bought a new one and hopefully this one will perform better like the rest of the family's.

I bought 2 units of this. one is more than 2 years old already and is still running perfectly. The other stopped working just after 2 years. since it was out of warranty I tried to open it and see why it won't charge or won't operate. I found several components have rust on it already. So am not sure if this model is water resistant to running water or not. At least 1 out of 2 is still working perfectly.

I'm obsessed with oral hygiene and this fabulous toothbrush meets all my needs and so stylish. It's been in my possession for under a week and I can't stop brushing my teeth....lol

Excellent, top rate cleaning. Perfect if you use it correctly (don't brush like a regular toothbrush etc). I have a crowded mouth so the smaller brush heads work perfectly for me.

First of all great product design, the body of toothbrush is silk and well quality made, plus the glass charger and travel package to complete the new generation of electric toothbrush era!

my teeth have never felt cleaner. Love the whitening function. The travel case is insanely cool with its usb power charger while its in the case. The two brush sizes is also a cool option. I now look forward to brushing my teeth.

Diamond Clean is the best toothbrush you can get, much better than the braun oral b.
The braun oral b is much harder on your teeth, but still cleans well.

The Diamod Clean is softer and cleans better.
Highly recommended.
