Description

With the Philips Sonicare Optimal White HX6066/88 Black (6 units), you can enjoy whiter teeth for 1.5 years. The bristles have a diamond shape. This way, they make better contact with the surface of your teeth and remove stains more effectively. Because the bristles are close together, you can also remove plaque easily. You should replace the brush attachment after about 3 months. Thanks to BrushSync, the toothbrush gives you a signal when the brush attachment needs to be replaced. This way, you¿ll replace it on time. This set lasts 1 year and 6 months.

Suitable for:
All Philips Sonicare models.

Excellent quality, but expensive.

Fine
Elegant
Firm
Pricey

I'm very pleased with the product. The toothbrush bristles stay fresh and good for a long time. And I think that's a big plus. After 4+ weeks of use, not a single hair has moved. And the bristles are still the original color.

The attachment looks nice and matches my black toothbrush well. On a pink Sonicare, it looks a bit odd. But okay, it's all about the quality.

Another nice thing: it comes with a cap that slides easily onto the brush. No complicated flaps.

The attachments are a bit pricey, but they do deliver quality. I wonder if they really need to be that expensive.

It's ideal that they come in a pair, because we have two Philips Sonicare toothbrushes at home.

Review is 8,7 out of 10.

Fine brushes

easy to use
Polish well
Nice color
Does not fit properly between the teeth

The Philips toothbrush head cleans well and generally provides a clean, thorough clean. It's easy to insert and remove, making it easy to use. The black color stands out from the often-standard white versions and can therefore offer an attractive, more modern look.

One minor point to note is that the brush has some difficulty cleaning between teeth with stubborn dirt. This could be related to the shape or hardness of the bristles. Nevertheless, the brush is perfectly adequate for daily use.

Very satisfied so far

Small attachment brush
Nice during pregnancy
Getting used to the vibration

I've been using the brush heads for a few weeks now to test them. The small shape of the brush head allows me to reach the back teeth easily, where other brands often make it difficult to reach the back of my molars, but this one doesn't have any problems. I'm currently pregnant, and this toothbrush (the head) makes brushing much better than before I started using the Sonicare. The shape of the bristles is supposed to whiten teeth or remove stains, but I can't really say for sure after such a short period. At first, I had to get used to the vibrations; when you brush your teeth, it's not an annoying or loud sound, but as soon as the plastic, rather than the brush, touches your teeth, it takes some getting used to. So far, I'm very satisfied, and I hope to see a difference in the whitening effect in the future.
