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.
