Question about Philips Sonicare 9900 Prestige

I think the results are good. But it's always worth looking at the price and promotions. Some of them are available for around 200 euros.

Yes, these toothbrushes can also be used without an app. The big advantage of sonic toothbrushes is that you only have to guide them along the edge of the tooth, no brushing movements are necessary. Cleaning is done by sound. Since the sonic toothbrush also gets between and under the gums, you really only need to place the brush at the neck of the tooth at a 30 degree angle and then move it along the gums.

By the way, there is not only Philips or Oral B, we Swiss also have our own sonic toothbrush product, developed by the company Curadent, the toothbrushes are called Curaprox. So it is worth looking at these products for two reasons, they are very well positioned in terms of price and because they are Swiss products, a Swiss company is directly supported. The products were also developed in Switzerland. Galaxus carries three Curaprox sonic toothbrushes that stand out from the competition in a few ways.
