Looks gorgeous & works a treat
This toothbrush is utterly fabulous. Very easy to use, the immediate connection to the phone app as soon as I pick up the brush is great, the brushing guide in the app is very helpful and afterwards my teeth feel fantastic. There is no need to try to remember the different functions of each toothbrush head because the relevant function lights up as soon as you attach the head. The charging glass is stunning and the carry case looks easy to use and is easy on the eye.I would definitely recommend this product.
Pros
Gleaming teeth, very easy to use, easy to change the heads, the phone app is very useful.
Cons
My only 2 slight niggles are that the charging base has a 2-pin plug. So I needed an adaptor to convert it to a 3 pin - which was very annoying. I would have expected Philips to provide me with the adaptor, considering the price of the product. Also, when trying to register my purchase online, the website instructions to obtain the serial number were misleading and when I contacted the helpline, the number i was instructed to use bore no resemblance to the serial number at the base of my brush. I have provided feedback and I hope the website instructions are improved to avoid others having their time wasted.

Sonicare Diamondclean Smart Electric Toothbrush
Highly recommended by my dental hygienist. Expensive but decided it was worth it as dental bills can be a great deal more, and it is so essential to look after one's teeth. Used the app most times as it encourages me to clean my teeth properly and twice a day - clean, floss and tongue. Great choice of brushes - the tongue brush and spray is not only getting rid of bacteria, but any bad taste in my mouth just disappears. My teeth have honestly never felt so clean and so white!

Good product better than the older diamond cleans
Old diamond cleans got gunked up but this one has a better seal also seems to be better power as well but time will tell.
