A great brush, not cheap but if you can afford it, you will if you follow the app have a good results
I was a bit sceptical on splashing out £205.00 on an electrical toothbrush but after my dentist getting on to me about not using my brush correctly, so causing bleeding gums due to excessive pressure etc
I thought it was about time I got on the case, being a big fan of gadgets I was instantly drawn to this toothbrush.
Setting up the app was a doddle, it tells you when you are over applying pressure, monitors where you have cleaned and where needs more attention, as different settings for what you are looking to achieve, i.e. sensitive, gums, etc.
In a nut shell, I think cause you are looking at the app and following the on screen instructions you are more likely to give it the full attention, rather than when you are regular brushing you can tend to rush.
This toothbrush beats my previous one hands down. I love the fact I can see where I need to do be more precise and not use so much force. Super easy to use would definitely recommend
