It could have less charging time and less noise from vibrations. APP is country-specific. It was almost impossible for me to use the APP as my play store is from different country.
We are happy to hear, that the results of your Sonicare are to your satisfaction. We also highly appreciate your feedback regarding the charging time and noise coming from the Sonicare. We will make sure to forward it directly to our responsible coleagues to hopefully have a better performance with our next model.
We continuously wish you shining white teeth and a great day. :-)
