The App needs a big improvement the brush is very good really like teeth feel very clean.
Shavers despatched the toothbrush for next day as advertised, excellent service and I'm very pleased with the product.
Used Diamond Clean for last 3 years. This one acts as good as the diamond clean collection. The app is a good feature, however, it needs improvement as it is not very convenient to use. You can only make the tooth brush smart when it is connected to the app, otherwise it is not smart at all.
