Philips 9900 HX9992/12

It worked very well for 2 years and then it started making funny noises and the toothbruh head was really wobbly. Customer Service have been very difficult to deal with even though I bought the product with them directly as they said it wasn't registered so I'm left with a very expensive toothbrush that doesn't work

Extremely disappointed. I bought the Sonicare Prestige 9900 expecting premium quality, but the handle developed the same fault twice. On both occasions, the metal drive shaft became loose, causing the toothbrush to vibrate loudly and become unusable.For a flagship product at this price, I expected much better durability. Customer service only offered a discount on a replacement rather than standing behind a product that has failed twice.Excellent cleaning performance, but reliability has been very disappointing. I can no longer recommend this model.

The toothbrush operates well. I like that it's easy to clean and the power button doesn't get blocked like it used to. The only issue is that the intensity setting sometimes resets itself. You have to keep an eye on it and reset it.

The philips HX9992 diamond clean toothbrush is awesome, although a bit expensive , however i waited for a black friday deal and it was still expensive but far cheaper than before. But what can I say it is great and that good i purchased another for my partner and she couldn't believe how well it cleaned her teeth. And the travel case is great too. Product support is awesome, as mine after about a year started to be a bit noisy with a common fault in which the screw holding the metal head plug worked loose. This was quickly swapped out by their support which was awesome as the brush was expensive in the first place. Overall wow it great and worth it.
